Ok long story short my PC is infested with viruses, trojans ect. I've used several anti-viruses and spyware programs but can't get rid of them. I've even formatted my system twice (in a row) using dos format and then windows xp install format. I then installed windows xp and an up-to-date antivirus and my pc is once again infected with countless viruses ect. Does anyone know of a really, really good format method that will completely annihalate everything on my pc? Clearly the standard format doesn't get everything, unless there's a virus on my windows xp cd... (fully legal so it's not that). Any help appreciated!
