Never been without an Antivirus program and haver never been infected (AV picks it out first). It saves me time, it saves me hassles, NAV2000 does not tax or affect the way my system runs, regardless of what others say, updates regularly available as and when are needed. If you don't use a AV program, don't complain when you do get infected as there are now viruses that hide in ActiveX features in web pages & email attached viruses that DON'T require the email or attachment opened or run to infect you.
To put it in perspective, running a PC without AntiVirus software is like sleeping with a person who is infected with HIV or another disease and thinking that there is the small chance that you won't catch anything. Even Linux isn't safe now......
