Re: Varioius questions
Viruses only affect software. It would be a very extreme circumstance if a virus affected any hardware. Because of this, if you just wipe the hard drive and start out with a fresh OS install, any effects of viruses will be gone. There is no need to get a new computer just because a virus destroyed your data.
The best antivirus software in my opinion is NOD32. NOD32 isn't free though. I'd say the best free one is avast.
The best pay antispyware is Spy Sweeper. The best free is Ad-aware.
