You’re mixing two things: First, you’re right this file I personally would not trust and keep quarantined. I don’t know Malwarebytes but Windows Defender back in the day only would get active on files you or your system interacted with -> would make sense that you only get one alarm. In addition, windows was notoriously bad with multiple virus scanners as they themselves show infection patterns in their behavior,(who else than a virus and a scanner wants to access literally everything you do?). So: i would err on the side of caution. But then there’s the question about the source. And here I can only ask you to be more careful: never trust a source more than your own defense layers. Even the most reputable file sources will have things that will harm you - including the Microsoft Windows updates themselves by the way. But here it’s more critical: don’t trust pirate sites. Ever. No matter how good their reputation. Oh and yadda yadda Linux blah but someone else will give that talk I assume ;) Stay safe!
