for taking care of your ad-ware problem i would suggest buying the pro version of Lavasoft Ad-Aware as yoo can use it to find existing adaware and eliminate it. As well it will run in the background like a virus checker and prevent new adaware from being installed.
Also for antivirus software try grisoft's AVG antivirus.
