Hi Several months ago i had a problem where a message popped up that said "What do you know it works". I feared remote access Trojan. I changed from AVG to panda antivirus. then i was having problems with slow internet and hard disk running for a couple minutes for no reason . I then added Malwarebytes.
Then got some BSOD errors. Switched to Avast somewhere in there. Had some problems with not having the right settings/allowances for MBAM and Avast, i got them fixed. For the last few weeks no BSOD errors
