Do you have a system restore/boot disk?

Check to see if any more than the basic four programs are running in the background - task manager/boot....remove superfulous

Run a virus program ON-LINE from any of the big providers.

Use CC-Clean to dump old files.

Use Ad-Aware - to remove the "go-to"'s

Install, and use Zone Alarm.

Do not pay a farthing for any of the above - all a available for FREE!
