What does the notification with Win32/Vigram.A detection mean?

The Win32/Vigram.A detection you can see in the lower right corner is shown to you by Microsoft Defender. That anti-malware software is pretty good at scanning, however, prone to be mainly unreliable. It is prone to malware attacks, it has a glitchy user interface and bugged malware clearing capabilities. Therefore, the pop-up which says concerning the Vigram is simply a notification that Defender has found it. To remove it, you will likely need to use another anti-malware program.

Is Win32/Vigram.A dangerous?

Adware like Vigram one is not something contrasty, compared to some other advertising malware. But as it was pointed out, the banners it demonstrates to you are quite frequently loaded with illegal content. Even if you can identify fraud from adware – do you really like looking at promotions for free? Especially ones that cover your web browser window and also distract you from your working process? It seems that we already understand the reply.

How did I get this virus?

It is hard to line the sources of malware on your PC. Nowadays, things are mixed up, and spreading methods utilized by adware 5 years ago may be utilized by spyware these days. However, if we abstract from the exact spreading way and will think about why it works, the answer will be really simple – low level of cybersecurity understanding. Individuals press on advertisements on weird sites, click the pop-ups they receive in their web browsers, call the “Microsoft tech support” thinking that the odd banner that states about malware is true. It is necessary to understand what is legitimate – to prevent misconceptions when trying to find out a virus.

Nowadays, there are two of the most widespread tactics of malware spreading – bait e-mails and also injection into a hacked program. While the first one is not so easy to stay away from – you should know a lot to understand a fake – the 2nd one is very easy to solve: just do not use cracked programs. Torrent-trackers and other sources of “free” applications (which are, in fact, paid, but with a disabled license checking) are really a giveaway point of malware. And Win32/Vigram.A is just amongst them.
