I just noticed on my 8.1 desktop on 12/3 a file was downloaded from Firefox that was quarantined as Bloodhound.Exploit.33. I'm paranoid now in wondering if this is a problem and if my machine is infected. My parents use this desktop, and it was around the time in the morning one of them usually uses it so I don't know what one of them did. It was quarantined so is it removed now? Or do I have to delete it still? I don't see any option to, only to restore it which I don't wanna do of course. I proceeded to downloaded Malwarebytes and ran it and it didn't find any threats. And it hasn't popped up since, either. It says file was released less than a week ago under info. Can I rest easy, or should I be worried?
