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
AVG - they also have a great anti virus program

Then I would try the the anti spyware. The link is on the same page above.





Unlike anti virus, you want to run multiple anti spyware.





Another anti spyware is Ad Aware.

Grissoft puts out a free anti virus that I would recommend to anyone.


Just remember one thing however, ONLY have one anti virus program running on your taskbar at a time. If you have two or more they will conflict with one another. The best way is to right click on one and choose Exit. This way ONLY one anti virus is running at a time.


Remember also to do updates or allow the application to do its own updates to keep the application current.


Good luck.
You can free download antispyware 2008
