Most antivirus products identify malicious software by comparing the software being run to pieces of known worm and virus code, called signatures. Primary Response, however, determines whether software is malicious based on a mathematical analysis of what it's trying to do.

This means that, unlike other products, Primary Response can protect users even from unreported viruses, Williamson said. The new version will be able to detect and remove spyware and adware, as well as malicious software such as viruses, he said.

This removal capability is new. The current version of Primary Response simply quarantines malicious software once it has been identified. But version 4.0 will be able to uninstall programs using these same analysis techniques.
