I have yet to find an application that detects adware and spyware before it's installed on your PC, so my recommendation is not to pay for adware/spyware removal software at this time. Simply use a combination of Ad-aware (freeware version) and Spybot - Search & Destroy to remove the offending software. I believe Norton is on the right track by combining antivirus software with adware/spyware-detection. With automatic updates and real-time detection, Norton could prove to be the ultimate removal tool for viruses, adware, and spyware. Only time will tell, and I'm sure McAfee has something up its sleeve as well.
