PossibleHostsFileHijack fills your personal computer with various ads, opens your web browser without your desire and makes the system unprotected to other malware infiltration.

Any malware exists with the only target – make money on you1. And the programmers of these things are not thinking of morality – they utilize all possible methods. Taking your private data, receiving the comission for the banners you watch for them, utilizing your CPU and GPU to mine cryptocurrencies – that is not the complete list of what they do.

That anti-malware software is pretty good at scanning, however, prone to be basically unreliable.

It looks that we actually know the reply.

How did I get this virus?

It is hard to trace the sources of malware on your PC. Nowadays, things are mixed up, and spreading tactics chosen by adware 5 years ago may be used by spyware nowadays. However, if we abstract from the exact spreading method and will think of why it has success, the explanation will be really basic – low level of cybersecurity awareness. Individuals click on promotions on strange websites, open the pop-ups they get in their web browsers, call the “Microsoft tech support” thinking that the scary banner that says about malware is true. It is necessary to understand what is legitimate – to prevent misunderstandings when trying to identify a virus.
