Hello,
I have this problem, where Avast keeps catching this virus called Win64:Malware over and over again for about 20 days now, and I'm not sure what I should i do about it. I added the logs from Malwarebytes and Farbar Recovery Scan Tool. The infected file is wmcodecs.dll and the location is C:\Windows\System32. I think the Avast background scanner is catching it. Maybe you could help me with this problem?
