I was already doing a full scan with Malwarebytes, and this is the log:

After that, I removed everything and rebooted the laptop, I did a quick scan. This is the log for that one:

It would seem like everything is okay now, but I still get that pop-up from Avast every few minutes. I would attach the OLT document and everything that comes after that (according to the guide), but OLT doesn't run for some reason. All I get is an "Application Error" message every time I run it, which says "Exception EReadError in module OLT.exe at 00016A6B. Error reading DiskParrtitionInfo1.Active: Server execution failed."
