This virus modifies the system configurations, edits the Group Policies and Windows registry. All of these elements are vital for correct system functioning, even in case when we are not talking about PC safety. Therefore, the virus which JS/Downloader carries, or which it will inject after some time, will try to get maximum revenue from you. Cybercriminals can steal your personal data, and then push it on the Darknet. Using adware and browser hijacker functions, embedded in Trojan:JS/Downloader virus, they can make money by showing you the ads.

How did I get this virus?

It is difficult to line the origins of malware on your computer. Nowadays, things are mixed, and distribution methods used by adware 5 years ago may be used by spyware nowadays. However, if we abstract from the exact distribution method and will think about why it works, the reply will be really simple – low level of cybersecurity awareness. Individuals press on promotions on strange sites, click the pop-ups they get in their browsers, call the “Microsoft tech support” believing that the odd banner that states about malware is true. It is important to know what is legitimate – to prevent misunderstandings when trying to find out a virus.

Nowadays, there are two of the most extensive tactics of malware distribution – lure emails and injection into a hacked program. While the first one is not so easy to avoid – you need to know a lot to recognize a fake – the second one is simple to solve: just don’t use hacked programs. Torrent-trackers and other providers of “totally free” applications (which are, actually, paid, but with a disabled license checking) are really a giveaway point of malware. And Trojan:JS/Downloader is just within them.
