I have used AVG Anti Virus, Zone Alarm Firewall, Spy-bot Search and Destroy and Ad Aware both spyware killers for years. They are all free for personal use and I have had no trouble with Viruses Trojans etc. AVG does not slow the system down as much as some other products and Zone Alarm allows a lot of personal configuration unlike the Windows Firewall. They can all be downloaded from the following linkhttp://www.computeractive.co.uk/. On the home page select downloads and then the appropriate category.I also use Windows Defender from the Microsoft site. It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. You should run A/V and anti spy weekly. Hope this helps

I would recommend getting spywareblaster, AVG antivirus, and Zonealarm Firewall. These are all free which is a plus and they work great. One thing to remember is that you have to be careful on what you download from the internet and the sites you go to, also don't open suspective emails. All these things will help you on the way to happy computing! I hope that helps.
get the AVG free antivirus software.
spybot will help you keep the spyware out and its free and has a tea timer that allows for continuous protection.
don't get free, it will probably have a virus in it...
