Norton antivirus I like because in this software the system will not get slow at the time of scanning task. The other most useful feature is the page of tasks divided into three categories and they are genera, backup and PC tuneup. It also has a set of quick control to turn components off or on.
I wouldn't stress too much when using Norton. I have yet to hear any horror stories from this anti-virus. Make sure you keep running the scan though just to make sure the Trojan Horses aren't still hiding in there.
