From Apex Software Solutions:
The Complete Protection System's System Scanner is different from other anti-virus and anti-spyware software, in that it doesn't just rely on signatures to identify threats to your computer but instead makes judgments itself. This means the System Scanner is much quicker at identifying new threats, and once one computer has identified a threat it informs all other System Scanners around the world about it. You have complete control over how the system responds to detected threats, allowing you to ignore, delete, kill or heal a threat. However if you are using a free version of the software some of these options may not be available.
