I was just going to also mention Microsoft Security Essentials. A member on another forum told us about it so I downloaded it. It has caught so many threats that I can't count them all.

I go onto cooking sites for recipes (Ok, I like to cook) and you would be amazed how many viruses are planted on those sites. Every so often a screen will pop up telling me the Microsoft program has detected a virus and I can click to clean it out. So far it has kept my computer clean.

That program is free and you can also do a quick scan or a complete scan (that takes about 5 hours) and it has always come up clean when I do it. I am very impressed with it so far, and love the fact it is free.
