I read a while ago that some people on here were recommending a good free antivirus program but I can't track it down. My wife got a new laptop and her old laptop won't be on the internet any more (except for very rarely). I don't want to pay for Norton for it, and I don't want Norton hogging all the resources. However I'd also like something on it that means if she does go on the internet it doesn't get virus ridden and die. Any suggestions?
