If you want a free anti-virus I recommend in order of popularity, but please choose the right one for you (install only one):

1. AVG Free

a. A simple interface (easier to use than Avast! and Avira)

b. Can detect about 82.82% of viruses

Cons: low virus detection

2. Avast!

a. Real-time protection

b. It has an option to delete a virus once found

c. Can detect about 87.46% of viruses.

Cons: Too many icons and confusing user interface

3. Avira AntiVir

a. It can detect malware better than Avast and AVG

b. It's cute umbrella icon

c. Can detect about 94.26% of viruses

Cons: A very sluggish update

Any of these can be downloaded to a disc - you will need to run this anti-virus in Safe Mode (tap F8 as the computer boots up and choose to boot to safe mode). It is also important to update the virus definitions once installed on your computer.

Go to http://www.free-av.com/ and download Avira Classic. Then go to http://www.avira.com/en/threats/section/... and download the latest definitions. After installing Avira, go to the update menu and click manual update..., locate the file and then scan.
Good question...
