All of these components are vital for correct system functioning, even when we are not talking about Windows safety.

Using adware and browser hijacker functionality, embedded in Trojan:MSIL/CoinMiner.MA!MTB malware, they can make money by showing you the advertisements. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners per day – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.

How did I get this virus?

It is difficult to line the origins of malware on your PC. Nowadays, things are mixed, and distribution tactics chosen by adware 5 years ago can be used by spyware nowadays. However, if we abstract from the exact spreading tactic and will think about why it has success, the reply will be pretty basic – low level of cybersecurity awareness. Individuals press on ads on weird sites, open the pop-ups they receive in their browsers, call the “Microsoft tech support” assuming that the scary banner that says about malware is true. It is very important to understand what is legitimate – to avoid misconceptions when trying to figure out a virus.

Nowadays, there are two of the most extensive tactics of malware distribution – lure emails and injection into a hacked program.

Torrent-trackers and various other sources of “totally free” applications (which are, exactly, paid, but with a disabled license checking) are really a giveaway place of malware. And Trojan:MSIL/CoinMiner.MA!MTB is just amongst them.
