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 available tactics.

Do you like to be a riding equine? That is a rhetorical question.

What does the notification with PWS:Win32/VidarStealer.MR!MTB detection mean?

The PWS:Win32/VidarStealer.MR!MTB detection you can see in the lower right side is displayed to you by Microsoft Defender.

It is vulnerable to malware invasions, it has a glitchy interface and problematic malware removal capabilities. Thus, the pop-up which states concerning the Vidar is just an alert that Defender has actually spotted it. To remove it, you will likely need to make use of another anti-malware program.

The exact PWS:Win32/VidarStealer.MR!MTB virus is a very unpleasant thing.
