You can download several Antivirus \ firewall\ anti-spyware programs from download.com.

Zonelarm firewall is good as is AVG antivirus ; and both are free
The best antivirus is active virus shield. The best firewall is zonealarm. Both free.
You can go to cnet .com and read the reviews for yourself, but remember that the programs are only as good as the upkeep of the user in other words run the scans and do the updates. Peace!

AV - according to people smarter than me:NOD32, (AVG and Kaspersky are OK too)
Personally, I use the AOL AntiVirusShield. Don't let the name AOL scare you. AntiVirusShield is made by Kaspersky which is one of top-rated anti-virus vendors in the world.

In recent tests, the most popular free anti-virus, AVG, was only able to detect about 82% of a very large sample of viruses. On the other hand, AntiVirusShield was able to detect better than 99% in the same test.
