The PUABundler:Win32/MSetup detection you can see in the lower right corner is shown to you by Microsoft Defender. That anti-malware application is pretty good at scanning, however, prone to be mainly unstable. It is unprotected to malware invasions, it has a glitchy interface and bugged malware removal features. For this reason, the pop-up which states concerning the MSetup is rather just an alert that Defender has detected it. To remove it, you will likely need to use another anti-malware program.

The particular harm to your system may be created not only as a result of the malware injection. A huge share of suspicious programs, like the MSetup application is, is just improperly programmed.

It is important to understand what is legitimate – to prevent misconceptions when attempting to determine a virus.
