Anti-Spyware programs do detect/protect some of the things an AV program will miss. I do not suggest adaware however, it's old school, and not what it used to be. MalwareBytes AntiMalware (MBAM) is the program you should have. The pro version will protect you from a lot of things that can get past your AV program. I use Comodo internet security, MBAM pro, and the free version of SUPERAntiSpyware, for on demand scanning. I, and most people that know a little about computer security would agree. MBAM is only 25 dollars for a lifetime license, a good deal for the protection it provides. I would get rid of adaware, and get MBAM at a minimum, and if you don't mind manually updating, and running scans every now, and then, SUPERAntiSpyware is the other choice.
