The best virus protections on the market

My dads whole business is building & servicing computers, & he DETESTS Norton. He's had so many computers come in with Norton on it that are just plastered with viruses. But I think it also really depends on what you do with the internet. Some downloads come with a whole lot of adware/spyware. So basically just run checks periodically. But the only virus scanner he will use is McAfee. He swears by it.

i would say norton, but norton isn't free you have to pay for it but when you have norton you can be more than 100% sure you gonna be virus free. Cause norton uploads a lot and does full system scans on a regulary base. It's really hard for virussen to get trough Norton!
