I’m using the free version of AVG on all of our machines for a number of years now and I’ve had no problems at all. Another excellent free antivirus/anti spyware program is Avast. These two free versions can be hard to find but they are available at their respective web sites. If you need/want help with AVG just ask.

Good luck and remember that excellent antivirus/spyware programs don’t need to cost you money.
