Remove “Microsoft Critical Alert” Pop-up Scam

In the article below we will be describing a version of a browser hijacker called “Microsoft Critical Alert” Pop-up. This kind of programs is known to cause certain trouble, but only in regards to your browsers – Mozilla, Chrome or Explorer, and to modify them in given ways. The possible modifications include a sudden change of your default search engine and /or homepage; the beginning of an annoying redirection process every time you try to load a web page; and an active production of pop-ups and other versions of online ads. Although hijackers are NOT the greatest threat you can come across on the web (they are not malicious and do not represent viruses), they could become increasingly annoying with time and that is why we have created this article – to help you understand their nature and remove the specific one that has infected your device – “Microsoft Critical Alert”.

Browser hijackers: only irritating or dangerous indeed?

This software family has not been known to cause any trouble. We have pretty much elaborated on the way they affect your browsers above. We can also say that “Microsoft Critical Alert”, for example, may have been programmed to access your browser history records and build a plan for generating ads based on your recent searches and potential interests. As a result, you will only see pop-ups and banners that are supposed to match your tastes produced on your screen while you are surfing the web. Also, sometimes the active redirection and generation of advertisements could become the reasons for a slowdown of your PC, which is highly unlikely if your computer has substantial system resources.

But what sets the hijackers and the viruses apart? The main reasons why “Microsoft Critical Alert” and its equally annoying siblings have not been identified as malicious, but only as potentially unwanted is the fact that they cannot self-replicate on your machine, self-infect your computer or damage any data in any way. Ransomware and Trojans, as typical malware, on the other hand, may greatly harm your favorite files, destroy them, corrupt them or hijack them. The real aim of browser hijacker programs in general is to promote products, services, web pages, even homepages and search engines. This is a completely legal branch of the online marketing industry and is NOT against any law. Their developers make a lot of money out of the generated ads and the rule: “The more, the better” really applies to this software. Such a program could seem to always strive to produce more and more pop-ups and to cause more and more redirections.

How and where is it possible to get infected with “Microsoft Critical Alert”?

Browser hijackers are legal and consequently, very widely spread. You can catch them from torrent and video-sharing web pages. They could be found inside websites as well.
