If you spectate the alert of Adware:Win32/PCAcceleratePro!MSR detection, it seems that your computer has a problem. All malicious programs are dangerous, without any exceptions. PCAcceleratePro!MSR fills your PC with different advertisements, opens your web browser without your intention, and makes the system vulnerable to additional malware injection.

Any kind of malware exists with the only target – generate profits on you1. And the programmers of these things are not thinking of morality – they utilize all available methods. Taking your private data, getting the commission for the ads you watch for them, utilizing your system components to mine cryptocurrencies – that is not the full list of what they do. Do you like to be a riding horse? That is a rhetorical question.

What does the notification with Adware:Win32/PCAcceleratePro!MSR detection mean?

The Adware:Win32/PCAcceleratePro!MSR detection you can see in the lower right side is displayed to you by Microsoft Defender. That anti-malware software is pretty good at scanning, however, prone to be generally unreliable. It is defenseless to malware attacks, it has a glitchy interface and problematic malware clearing features. For this reason, the pop-up which says concerning the PCAcceleratePro!MSR is simply a notification that Defender has actually recognized it. To remove it, you will likely need to use a separate anti-malware program.
