Sorry for the late reply. I was on vacation and you said that you could only reply on weekends so I thought that as I was going to return at Saturday then you'll find a response in order to follow it in the weekend.
For avast's report:
Go to C:\ProgramData\AVAST Software\Avast\report and you'll see some text files there.
One of them should be named Full System Scan.txt
Copy its contents and paste them here
If there's no such name, tell me what logs are there
Did you do the final step of my previous post?
