CounterSpy
CounterSpy is a powerful spyware and malware remover that treads lightly on system resources. It's a powerful Antispyware tool that does not bog down your PC. Long, "heavy-CPU" spyware scans are a thing of the past. With CounterSpy's small memory footprint, you don't have to choose between PC security and PC performance. If you are running another security product with its own real-time protection, and see an impact on system performance, we recommend you disable CounterSpy Active Protection.
Version 3.1 revamps the user interface, speeds up scans, and uses less system resources.
