Gene, download cc cleaner available from several sources. Configure it and then clean your computer. This might help. Don't forget to reboot after it's done. When you download it, uncheck the box that downloads another browser unless you uncheck it. cc cleaner is a great, free program. I would do a cursory cleaning of my computer BEFORE running the cc cleaner program itself. This will speed things up considerably. I think you need to do both cleanings though, not just the one where you dump things from your browser. You might want to consider Ghostery if you're running Firefox too. Look in the same apps section where you got adblock IIRC.
