The absolute best AntiVirus software is a Full System Backup. Not the stoopid restore thing that requires you to start the virus to start the restore, but a regular Backup Routing so when a virus or whatever does happen, and it will, you havethe clean data image safe and unaffected. PERIOD

Yes use an AV, AVG grisoft is good, but n Anti Virus is only as good as the most recentg update, and the update comes after the virus has been launched, so the backup is the only sure and proven method for data saftey and failure of loss.
an external firewall would help but wouldnt help you for downloaded viruses streamed via browsers. I recommend using Ad aware se personal for spyware and scanning for viruses with norton antivirus. and remember to set restore dates frequently.
