After removing some other malware that I got from a bogus download, I restart my computer to a pop up that says my antivirus (Avira Free Version) and Windows Security are both disabled. Whenever I try to start them, or any other antivirus program, I get a pop up that says "Requested resource is in use." I searched this up on my laptop (what I'm using while my infected desktop is unplugged) and tried solutions from other threads. I downloaded Rkiller, Chameleon, and Malwarebytes Anti-rootkit onto a flash drive and tried to use them on my desktop in minimal safe mode but I still got the same pop up. It seems like the rootkit only affects antivirus software but I still don't want to risk connecting to the internet longer than necessary so my desktop has been off ever since. I'm on Windows 10 and my desktop is custom built.
