I quit Windows Defender and switched to Avast Premium Security (yes, the paid one), in order to have a better protection. I use my pc for gaming, youtube facebook, movies etc. Today i turned on my PC, at first it gave me a warning and then rebooted. It turned on again and i noticed that avast didn't startup with the system (boot was slow by the way). I knew from the start that something was happening so i checked the programs list (screenshot 1). Avast didn't EXIST! I went to services so i can restart it. Nothing again (screenshot 2). I downloaded Malwarebytes because windows defender was also disabled. The results were amazing i had a trojian and a bitcoin miner! I will attach these so you can investigate. After malwarebytes quarantined them, avast popped up again with it's passive mode turned on, and the classic message "MY COMPUTER IS PROTECTED". So thanks avast PREMIUM for protecting my computer, i don't even know what these malware did.
*Just for testing avast, i restored a malicious file from the quarantine and scanned it with avast PREMIUM. Don't mind it was clear. (Test picture)
