Hmm. I checked the settings and quick scan and full scan settings and the sensitivity for quick scan was on normal and full scan was on thorough, both with use code emulation checked. I tried it on the settings you had in the screenshot, and I set up the same custom scan and I still got the PID rootkit detections.

This is pretty strange to me, I’ve calmed down a bit as I have now come to doubt this is actually malicious rootkits it’s finding. Earlier after I did a full scan in malewarebytes it found nothing. And then after scanning it with a quick scan again shortly after malewarebytes finished its scan the quick scan got nothing. However, right after the quick scan finished I did a full scan, and it instantly got 500 rootkits. (Much smaller number than before.) And every further scan got around 500 rootkits. Not sure what happened to make the number go to 0 and then to 500.

As of right now if I scan it gets around 800 of them every time I scan, the number going steadily up. I’m becoming curious if this is avast detecting itself, somehow? (I’m not sure if that’s possible…) I’ve also noticed that my avast program appears to be behind a few versions… (it’s 5.1.889) I do however have the same virus definition version as you. (111024-1) I have yet to update the program version since it wants me to restart my computer to do so, and I’m still paranoid about restarting it. I guess I should do that, though.

I’ll try to contact the staff about this, I assume I can do that by just submitting a ticket.
