What does the notification with PUABundler:Win32/MSetup detection mean?

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.

Is PUABundler:Win32/MSetup dangerous?

I have actually mentioned that PUABundler:Win32/MSetup PUA is not as safe as it claims to be.

That still does not say that you need to panic – probably, this nasty thing has not succeeded to do negative things to your PC.

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. Possibly, their actions are rather effective than useless if done on certain system configurations, but not on each one. That’s how a simple system optimization app can trigger chaos with continuous BSODs on your system. Any type of interruptions to the system registry are dangerous, and they are even more risky if completed with such programs.

How did I get this virus?

It is difficult to line the sources of malware on your PC. Nowadays, things are mixed, and distribution ways chosen by adware 5 years ago may be utilized by spyware these days. But if we abstract from the exact spreading method and will think of why it has success, the reply will be very basic – low level of cybersecurity awareness. Individuals click on ads on weird websites, open the pop-ups they receive in their browsers, call the “Microsoft tech support” assuming that the weird banner that states about malware is true. It is important to understand what is legitimate – to prevent misconceptions when attempting to determine a virus.

And PUABundler:Win32/MSetup is just amongst them.
