You should use Norton Antivirus it's the BEST!

If you're running win XP or newer you have a firewall turned on by defalt. Do not use it do not trust it. Go out and buy Nortons Firewall (all listed on the url I gave) DO NOT USE Zonealarm Firewall it's a peace of JUNK that does not work and it does not keep out hackers.

If you're going to alot of photography sites then most like you DON'T have Virus on you're PC you have spyware. Programs Nortons will help to some live delete thoes programs but will not delete all of them. Do a yahoo search on spyware and it will bring up alot of spyware Remover programs most of wich are free.

Spybot Search and Destroy (S%26D) is a good program to use to speed up you're PC. From safer-networking it's the last url I listed.
