Norton now days is so popular now that hackers know they need to make their viruses immune to it. My dad doesnt believe me but I dont think his Norton has not been working correctly. Doesnt detect like it should.
AVG Anti-Virus free version hasnt let me down and it has constant updates. Look
here for more info. Combine that with those Anti-spyware software in the stickied thread in Computer Talk section of this forum. And for extras maybe a software firewall. I can look one up if you want.
EDIT: After looking into it ZoneAlarm seems to be a great firewall. More info click
here. And the free version for personal use is
here.
Surf safely.
