You can download and scan your computer for free.

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. 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

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.

definately AVG
