A highly acclaimed anti-spyware program by CA, which operates under the name of eTrust PestPatrol Anti-Spyware. CA Anti-Spyware is a very good complement to antivirus protection for detecting and removing spyware from adware, keypad strike detection programs (to steal passwords or other important private information), as well as Trojan horses, DoS (Denial of Service) agents, malicious ActiveX controls and other Internet threats that exploit existing vulnerabilities in system security and applications installed on computers (e.g. back door programs).

The main advantages of the program are the low number of false alarms and high scanning speed.
