my customer gave me the computer beecause it was slow and they couldn't get on the internet. when i first started working on the computer it was saying that it needed an update sp2 or sp3 in a moment of frustration i broke my rule and updated the computer before removing the virus. that was a big mistake the computer begin showing binary code and hasn't started or gone to safe mode since i made that blunder. now when i turn on the computer it shows the dell page and than it starts flashing binary code. it won't start or go into safe mode. so i tried putting the hard drive of the vista computer in another working computer as a secondary hard drive scan the system with superantispyware, malwarebytes antimalware, malwarebytes rootkits, bitdefender. this did find some of the malware, but it didn't solve the issue. when i put the hard drive back i was seeing the same problem.
i would appreciate any direction you can give thanks.
