I ranted on the other day about people not having anti virus software or firewall software but I did not offer any useable advice. So here are a few pointers. Get an anti virus program. Norton is excellent but you have to pay - it is probably worth it though, especially if you don't want to be messing about with hunting down the final remnants of the Virus yourself. I personally use Grisoft's AVG. I really like this and would highly recommend it. It is also free which helps out quite well. The latest version can be found at: http://free.grisoft.com/doc/2.
Anti-virus programs don't take care of every sort of malicious program that could screw up your computer so I would recommend installing some anti spyware programs. I personally use a combination of Spybot, HijackThis, Spyware Blaster, Ad-Aware. These can all be found with a simple google search and in general the basic version is free. Give them a go you might just fin that your computer is running a little faster.
