Webroot Spy Sweeper

The bad news is that Spy Sweeper isn't free. The good news is that it's worth every penny of the $30 registration fee. Spy Sweeper's real-time protection shield is one of its major advantages, alerting you when unwelcome guests attempt to clandestinely infiltrate your machine. The program's scanner is fast, and results are nearly flawless, thanks to Webroot's top-notch research-and-development team. Even though we recommend you keep multiple antispyware solutions close at hand, Spy Sweeper is powerful enough to act as a standalone solution.
