Needless to say, by depending on discarded computers I have become expert at cleaning them up considering that it is the malware that got them into my hands in the first place.
Malware really works out for me, their computers get slow and glitchy, so they buy new and I move up.
When you don’t care about the contents of the drives, it’s amazing what you can do to cleanse viruses. Wipe the drive, march 1s and 0s across the drive, and start from scratch. Simple, really. Its when really nasty viruses cause hardware damage...ah, there’s the rub.
