A month ago my PC detected a virus on my usb drive, I have avast and it removed a file called "autorun.inf" I also had AVG and it detected some type of trojan at the same time and removed it, (i dont have AVG anymore so I can't tell you exactly what it was).
My computer has been acting really weird lately just in the last couple of weeks at the startup it always freezes when I get to the opening screen and if i restart it it still just freezes. The only way it works is if I let the battery run out and then turn it back on.
I have avast and microsoft security essentials, and then i also ran malwarebytes and superantispyware and nothing says i have a virus.
So what else can I do to tell if a virus is infecting my computer and my usb stick?
thanks so much!
