The Adware:Win32/Zapchast.B!MTB detection you can see in the lower right corner is demonstrated to you by Microsoft Defender. That anti-malware program is good at scanning, however, prone to be mainly unstable. It is vulnerable to malware attacks, it has a glitchy user interface and bugged malware removal capabilities. Thus, the pop-up which states concerning the Zapchast.B!MTB is simply an alert that Defender has actually detected it. To remove it, you will likely need to use another anti-malware program.

The exact Adware:Win32/Zapchast.B!MTB malware is a very undesirable thing. This malware shows you a marvelous quantity of ads. Have you ever saw the doorway pages?

Adware Summary:

Is Adware:Win32/Zapchast.B!MTB dangerous?

Adware like this one is not something contrasty, compared to some other advertising malware. However, as it was mentioned, the banners it demonstrates to you are pretty frequently loaded with illegal content.

It looks that we actually understand the reply.

How did I get this virus?

It is hard to line the origins of malware on your computer. Nowadays, things are mixed up, and distribution tactics used by adware 5 years ago may be used by spyware these days. But if we abstract from the exact distribution tactic and will think about why it works, the answer will be really simple – low level of cybersecurity awareness. People click on ads on weird sites, click the pop-ups they receive in their web browsers, call the “Microsoft tech support” assuming that the scary banner that states about malware is true. It is necessary to understand what is legitimate – to stay away from misunderstandings when trying to find out a virus.

Nowadays, there are two of the most extensive ways of malware spreading – lure emails and injection into a hacked program. While the first one is not so easy to evade – you need to know a lot to understand a fake – the second one is easy to address: just do not utilize cracked applications. Torrent-trackers and various other providers of “totally free” applications (which are, actually, paid, but with a disabled license checking) are really a giveaway point of malware.
