I am running AVG, Spybot and Malwarebytes AM. The resident shield in AVG detected a trojan horse (BackDoor.Generic12.BPKA) in the file WINDOWS\System\driveasyncmac.sys - AVG has indicated this is a white listed file.
I have run my AV programs and they haven't located any more viruses or the same virus again, also Malwarebytes AM has not indicated it has located anything in the registry files etc.
My questions ;
Is the virus deleted ? Can / How do I delete / fix the whitelisted file ?
The computer in question is a laptop, it is connected via a router to my desktop and one other laptop, I have scanned these other computers and nothing has been located, are they ok ? Can a virus transfer over the router ?
Any other info would be greatly appreciated, I have searched all over the internet and read a lot of articles, all with different suggestions.
