Remove .Osiris File Virus Ransomware

Remove .Osiris Virus File Ransomware in just a few easy steps with our removal guide which works with all versions of Windows.

Below we will be describing .Osiris. This Ransomware-based program is known to enter your computer on its own, no approval necessary, and scan all your drives and disks for the data that is most commonly used. After that, the virus proceeds with encrypting these files and making it impossible for you to reach them in any way.  We have compiled this article to inform you about all aspects of this malware you should be aware of, and how to safely deal with it.

Characteristic features of all Ransomware programs

All Ransomware viruses are programmed to lock something on your PC, and ask for ransom afterwards, in order to unlock what they have blocked. Below in the paragraph about the versions of Ransomware you will see what such a virus could encode. Also, in every recorder case, the affected user has received an almost scary ransom-demanding message, including deadlines and preferred ways of paying the required sum of money. The viruses based on Ransomware could actually be divided into several major groups:

  • Ransomware that encrypts data: This is the scariest and the most widely-spread subtype of this malware. .Osiris, the program we are discussing, is also categorized as such. This means that these file-encrypting versions of Ransomware are fully capable of invading your PC, finding out which files exactly you normally tend to use; and making all these files inaccessible to you. Such an infection is generally among the hardest to be fought as you may remove the virus, but your files may be lost forever. Or you may complete the payment, but the hackers may decide not to give you back the access to your data and you may lose both your money and your data. Or another possibility is that your entire system may need to be reinstalled if you are unable to remove the virus itself.
  • Ransomware that attacks mobile devices: This kind of Ransomware is NOT used for the encryption of any files – it is normally exploited for the blocking of the screens of all your mobile devices such as smartphones, phablets and tablets. Your files are not in danger, but that virus could cover your entire screen with the ransom-demanding message, that you may not be able to reach anything on your device before completing the payment of the ransom.
  • Ransomware that attacks the desktops of computers: This subgroup of viruses resembles the mobile-oriented Ransomware. It functions in exactly the same way; the only difference being that this kind is computer-oriented – laptops and PC’s are its main targets. Again, your desktop/ monitor will be locked and you will be supposed to pay a ransom in exchange for the opportunity to access it back again.

Is it possible to fight them?

It is a very tricky question. If spotted in time, it may be able to prevent .Osiris from completing its malicious task. Unfortunately, this happens only to few users – they experience a slowdown in their PC’s performance and they check their Task Manager to see what has been going on. When they notice a strange process there that is using the most RAM and CPU, the only solution is to turn off the computer and NOT start it before contacting a specialist. In case the infection has already been completed and you have received the warning notification, there is little that can be done. Whatever you do will be risky at that point. What we advise you is to avoid paying the hackers, as there are other possible options like the Removal Guide below. Please, understand that you cannot really make sure that you will save your files, you can only hope for the best. At least, do not risk your money. And of course, the best way to fight such a deadly virus is by not catching it in the first place.

What to avoid, in order to stay away from .Osiris?

The best you can do is to stay away for the most usual sources of Ransomware, which are:

  • Spam in any form: Spam letters inside your emails might contain Ransomware, as well as their attachments. Also, the pop-up ads that you normally see on the web could also be contagious. Just avoid all of them as often as you can.
  • Illegal software / video/ movie/ music sources: To use programs and to download films and songs for free could be tempting, but it is recommended that you shouldn’t do that. Such places frequently contain all sorts of malware.

Last but not least, invest in a really good anti-malware tool. This you will never regret. Such tools have the latest virus databases and could protect you from various threats.

.Wallet Virus File Removal And Decrpytion

Remove .wallet Virus File Ransomware in just a few easy steps with our removal guide which works with all versions of Windows.

In the next several paragraphs, we will be talking about a virus known under the name of .wallet. This particular piece of malware is one of the newest members of the infamous Ransomware family. This kind of harmful programs is known to target users’ personal data, but instead of outright destroying it, they lock the files via a sophisticated encryption and later demand ransom in exchange for the decryption code.

The rising menace

Currently, the Ransomware type is one of the most feared and dangerous software threats and it does not seem to be losing momentum. Newer and more advanced programs of this kind are developed on a daily basis and security software companies have a hard time keeping up with the ever increasing pace of Ransomware. Therefore, we must ensure that our readers are well informed in regards to this threat and know how to protect their computers from it. In this article, you will be provided with some invaluable information and tips concerning .wallet, so make sure to read everything we have to offer. We will provide an in-depth explanation on how Ransomware viruses actually work and what you can do to stop them from completing their task. Also, for those of you that have already had their files locked by .wallet’s encryption, we have a removal guide that will help you deal with the virus infection and possibly restore the access to your documents without the need of paying the ransom.

Ransomware viruses often remain undetected

One of the things that makes .wallet and other malware of its type so dangerous and problematic is the fact that a lot of times antivirus programs fail to recognize the threat. This is because of the method that these viruses use when locking your files, namely – the method of encryption. You see, encryption as a separate process is not a bad thing. It is actually quite useful when software developers want to provide their product’s files with an extra layer of protection. However, Ransomware programs use that against you by applying the encryption on your personal data, thus rendering it inaccessible. As we already mentioned, encryption is commonly used by regular and legit programs and not only by Ransomware viruses. Therefore, most of the time antivirus programs regard such processes as harmless and let them continue. That way, .wallet is neither detected nor interrupted and is thus free to proceed with its noxious agenda.

Mind your PC behavior

Most of the time encryption processes do not finish in an instant. This is because of the way they work. First, the targeted files get copied and the copies that are created are actually the ones with the encryption code. After that, the original data is deleted and the end result is that each of the initial files has been made into an identical, locked copy. All of this can take substantial amounts of time, depending on your system and how much data you have stored on your HDD. Also, the Ransomware would require significant amounts of CPU time, RAM and free hard-drive space in order to complete its task. This allows you to spot the infection if you are vigilant enough. Therefore, make sure that you frequently check your Task Manger and see if there is an unusually high amount of system resources consumption without any visible reason. If you notice any of that, it might be due to a Ransomware attack, in which case the best course of action would be to shut down your machine and call for professional aid.

Concerning the ransom

When most Ransomware viruses succeed in locking the user’s data, they display a message, in which ransom is demanded and instructions on how to make the transfer are provided. Bitcoins are the usual currency, since they are untraceable and the criminal is able to retain full anonymity. If you’re currently in this situation and are contemplating paying the ransom, know that this is a really bad idea. There is absolutely no guarantee that you will be granted the key for your files, regardless of whether you make the transfer or not. A much better option is to try our removal guide below the next paragraph. We ought to mention that it might not work in all cases of Ransomware attacks, but it’s still worth the try and costs you nothing.

Preventing future infections

The next couple of rules, though simple and easy to follow, are extremely important when it comes to ensuring the security and safety of your computer and data for the days to come.

  • Download and install a high-quality security/antivirus program on your PC. In many instances .wallet gets to people’s computers through another virus that provides the Ransomware with direct access to your system. To prevent this from happening, you would need good and reliable security software.
  • Be careful when browsing. A huge number of users get their computers infected by .wallet because they have visited some illegal and sketchy website or downloaded something from an unreliable download source.
  • Meticulously check the details of newly received emails since if any of them are spam, they might contain the Ransomware. If you suspect that any of your new messages is some form of spam/junk mail, make sure to directly delete it.
  • Make sure that you have backed-up all important documents and other files so that even if Ransomware attacks and locks the ones on your PC, you will still have your data on a separate device that is untouched by the virus.
    • Important note: If you suspect that .wallet has attacked your PC, DO NOT connect any devices such as smartphones or flash memory sticks in an attempt to save your data, since those devices might get infected as well, making the matters even worse.

.zzzzz Virus File Removal And Decrpytion

Remove .zzzzz Virus File Ransomware in just a few easy steps with our removal guide which works with all versions of Windows.

Unlike other forms of malware, instead of trying to damage your system or data, Ransomware viruses use a technique called encryption to lock your files and then demand ransom for the decryption key. Due to their unique approach, this particular type of viruses is almost always devastating and the worst part about them is that in most instances the user never realizes what is happening until the malicious program has finished carrying out its agenda. Lately, there have been a number of reports concerning yet another virus of this type with the name .zzzzz. Since we believe that awareness is the best way to counteract any sort of malware here, in this guide, we will provide our readers with an in-depth explanation of how Ransomware programs such as .zzzzz work and how you can stop them from locking your files by encrypting them with their code. You will also be presented with a removal manual that also contains a list of decryptor tools for a number of Ransomware viruses. Therefore, if Ransomware has already locked your data, you can use that guide and see if it solves the problem.

Awareness

As we mentioned earlier, the majority of users remain completely unaware of the Ransomware infection until their files have been rendered inaccessible by the virus. This is because most security programs have a hard time spotting the process that is ran by the virus. The reason for that is the utilization of the so-called encryption. Encryption processes are a widely used file protection method that is commonly employed by a large number of legal and non-malicious programs. This is why when .zzzzz initiates its own encryption process, your antivirus might not target that as a threat and let it slip under its radar. The virus would then go on to lock all your personal documents and files without being interrupted or even spotted by you and after it has completed its malicious task it will start blackmailing you. Usually, once all data has been made inaccessible, Ransomware viruses display a notification that demands a certain amount of money from the victim in return for the said key. Bitcoins are the preferred method of payment, since they are a cryptocurrency that cannot be traced back to the hacker. Most of the times there will be instructions within the message on exactly how to execute the transfer.

Vigilance

The threat of getting attacked by Ransomware is increasing each day and with every new addition to the Ransomware family. It is extremely important that users remain vigilant and observant at all times because they might just be able to manually spot and intercept a Ransomware infection. The only real flaw of the encryption method is that it usually takes time and even though your antivirus might not notice it, you can technically do that yourself. .zzzzz does not instantly force its code on you original files. In fact, it creates copies of them, which are actually the ones that are locked by it. After that, the virus makes sure to delete all of your original documents so that you are left with the inaccessible copies. The copies themselves are intact, it’s only that you cannot open them without the key.

Obviously, a process such as this one is prone to take some time and require substantial amounts of system resources such as CPU time, HDD space and RAM. An observant user would be able to spot the difference in their PC performance and the unusually high use of its resources. If you happen to notice anything like that and there is no any visible reason for it, you might be currently under the attack of .zzzzz. In that case shut down your machine immediately and call for professional aid. Also, you must not connect any smartphones, flash memory sticks or other external devices if there is Ransomware on your PC, since they can be attacked by it as well.

Decision

Unfortunately, most people fail to address the threat before it’s too late and their files get locked. In this case, there are not many options to choose from. Many get tempted by the idea of getting it over with by simply making the ransom payment. However, this is exactly what the hacker’s goal is. Furthermore, you can never know if you are actually going to get the key even if you send the demanded money. Ransomware victims need to understand that making the transfer is a really bad idea. Our advice for all who have had their data locked by .zzzzz is to try our removal guide located below this article. We cannot guarantee a hundred percent success in all instances of Ransomware infection, but it is undoubtedly a much better alternative compared to sending money to an anonymous online criminal.

Precautions

There is simply no better way to handle Ransomware viruses than to make sure that they stay away from your personal files. For that reason, we have provided our readers with a short list of rules and tips that will help them fend off any future Ransomware attacks coming their way.

  • High-quality software protection – Invest in a reliable antivirus program, because many times Ransomware viruses get onto people’s computers through other viruses that serve as backdoor and a good security software would help you stop those.
  • Spam – Do not open shady e-mail messages or links since they might be malicious spam that carries the Ransomware with it.
  • Safe browsing – Always make sure that you only visit and download content from reliable websites. Never go to sites that are illegal or seem sketchy/potentially dangerous.
  • Data backup – this is an extremely important and effective precaution – backup all files that are important to you and even if .zzzzz gets into your system and encrypts everything there, you will have a safe and accessible copy of each important data file.

Aesir Virus File Ransomware Removal

Remove .Aesir Virus File Ransomware in just a few easy steps with our removal guide which works with all versions of Windows.

Whether you have heard about it before, or you are facing it now, having a good understanding of threats such as Ransomware can really be a life saver. This type of malware has been rapidly spreading and infecting users worldwide with unheard of success. One of the latest representatives of this notorious Ransomware family is called Aesir, and in this guide, we are going to discuss its methods of distribution, infection and file encryption. If you stay with us until the end, you will find out more about the ways you can protect your system and prevent its infection as well as a removal guide that may help you remove the malware if it has invaded your computer.

.aesir file virus ransomware
aesir file virus sample

Aesir: a better understanding of the threat

Aesir is yet another dreadful addition to the Ransomware family, which puts a challenge to security experts and anti-virus developers to come up with an effective solution to the threat. As a typical cryptovirus, this malware gets inside your machine undetected, locks all your data through a file encryption algorithm and requires you to pay a huge amount of money as ransom if you want to get your files back. The file encryption is not an actual malicious thing, and it is used by many institutions and organizations as one of the safest and most secure data protection methods. However, when incorporated in a criminal blackmail scheme where unscrupulous hackers lock your data to blackmail you, it could be a very malicious action. And what makes it even worse is that a threat like Aesir usually gets transmitted with the help of a Trojan horse that creates a vulnerability to the infected system and helps the cryptovirus remain undetected by the antivirus software while it silently performs its malicious encryption.

The process of encryption and the symptoms…

The Aesir encryption process usually takes some time until it is completed. Once the malware finds its way through the security holes that the Trojan has created, it starts to immediately infiltrate the system for commonly used files such as documents, music, images, games, movies, projects and all sorts of data found on the drives. Then, it starts to convert them all to a very complex combination of symbols that become impossible to open with any program. The threat tries to remain undetected while performing its malicious encryption, but in some cases, the process could be manually detected if the victims notice the unusually high amounts or RAM and CPU usage. The computer may significantly slow down as well. In such case, the best is to quickly unplug the device from all the networks and external devices and shut it down. Then, do not turn it on until you contact a security specialist if you suspect that a Ransomware has been invaded it.

If the files have already been encrypted…

Unfortunately, in most of the cases, Aesir is revealed only after it has encrypted the victims’ files and has placed its demands on the screen in a disturbing ransom note. The hackers behind this Ransomware usually promise to send the victims a secret decryption key, which will unlock the encrypted files if the required payment is made. Normally, they ask for payments in Bitcoins, which ensures that the transaction is untraceable and the crooks cannot be detected by the authorities. If you have been

.aesir file virus ransomware
aesir file virus sample

prompted to that scheme, we should warn you that this is a trap. The crooks are only interested in getting your money and it is very unlikely that you will really get the promised decryption key, let alone to decrypt your files. Moreover, there is absolutely no guarantee that if you get any key it will work, but if you agree to pay, you will surely give your money to a group of cyber criminals, who will keep terrorizing you and other users on the web. Therefore, removing the Ransomware may be a better idea and in the guide below we will show you how you can do that. And even though we cannot guarantee that it will restore your computer to the state it was before the encryption, it is still a better alternative to the ransom payment that may remove the nasty threat from your machine.

How to prevent Ransomware?

Protecting your computer and all other devices against threats like Aesir is the best you can do if you want to minimize the changes of getting infected. For that, the best is to avoid clicking on suspicious content on the web such as randomly popping ads, aggressive pop-ups, spam emails, various attachments, torrents and sketchy sites as this is where Ransomware likes to hide the most. To prevent system vulnerabilities, always update your system to the latest version and make sure you are getting the latest security patches. A good antivirus may also be of help when it comes to detecting such threats, but the good old backups are still your best chance, so make sure you regularly backup all your important data, this way even if you get infected, you could easily restore your files.

.Thor File Virus Ransomware Removal

Remove .Thor File Virus Ransomware with our free removal instructions which also cover how any .Thor File file can be recovered.

Countless threats are waiting for us on the Internet. Among the worst of them, we can distinguish the so-called Ransomware. This is a type of malicious software that is responsible for blocking your data or your screen and then demanding a ransom for giving the access back to you. The particular program discussed in this article is named .Thor File. Specialists in the field identify it as file-encrypting Ransomware. Below we will describe all the subtypes of this malware and we will give some specific details about this particular virus.

Ransomware: nature and versions

The viruses based on Ransomware are extremely invasive and dangerous. They need no permission to enter your PC and perform whatever they have been programmed to achieve. Here is a list of the different versions of Ransomware and what they do.

  1. Normally, the most common type comprises of the programs that encrypt files. They infect your computer, scan your drives, define your most cherished files and encrypt them. Then you usually receive a notification stating that you need to pay ransom for the encoded data. .Thor File belongs to this widely spread and extremely hazardous subtype.
  2. Another pretty common type of Ransomware is the so-called screen-locking version. The programs from this group are known to simply make your desktop unavailable to you by hiding it behind the ransom message pop-up that appears. In that message you will see all the information about the different payment methods you may use for sending your money to the hackers and accessing your screen again.
  3. Sometimes Ransomware may affect your mobile devices as well. The mobile-devices infecting Ransomware works in a way similar to the monitor-blocking subtype. It only makes the screen of your device inaccessible and the ransom payment is required again.
  4. Even the ‘good guys’ – the police and other state agencies may use such viruses to punish cyber criminals and make them pay for whatever they have done. So, we can say that Ransomware at least has one positive usage.

Of course, as you might expect, new viruses appear every day and this list will need to be updated with time, as there may appear new possible usages for the Ransomware-based viruses. Another important point of this article is the list with all the potential means of infecting with such a dangerous virus.

How your computer may end up infected with .Thor File Virus

Hackers use various methods to spread these malicious programs around the web. However, there are a few possible sources you should be particularly careful with:

  • Never trust any pop-up you come across on the web: Often the ads you see on the Internet are harmless and have marketing purposes. Nevertheless, as you cannot distinguish the bad ones from the good ones, we recommend that you stay away from them all. Just a click on the wrong one and your PC might end up contaminated and you – harassed.
  • Do not click on any random notification that appears on your screen. Even the update requests might be fake and may lead to contagious web pages. Sometimes these malicious programs are capable of sending tempting notifications that look like the original system-generated ones. However, avoid them all and manually look for updates using the feature built in your Control Panel.
  • Always stay away from all kinds of emails and their attachments if you cannot recognize the senders or the topics sound suspicious: Sometimes .Thor File might come from a letter inside your email (usually together with other malware – a Trojan) or from its attachments. Even images and documents might infect you with this virus. Do not download or open anything suspicious.
  • Torrents, certain websites and shareware, as well as streaming pages, might be contagious. Be careful! Just use your common sense while surfing the web and you will never go wrong and end up contaminated with malware of any kind.

.Thor File Virus Ransomware Removal

Step 1 – hunt for active virus processes

To do this, you will have to make use of your Task Manager. Use the R-Ctrl+Shift+Esc key combination in order to open it. Now, go to the Processes tab and sort the list by order of CPU and/or memory used. Now, look through the list – if any process is using up very high amounts of memory or has a suspicious name or description, then it might be a process ran by the Ransomware. End that process immediately and move on to the next step.
