CA Anti-Spyware is a spyware detection program distributed by CA, Inc. Until 2007, it was known as PestPatrol.
PestPatrol was first issued in 2000 by PestPatrol, Inc. Among its unique features were CookiePatrol, which purges spyware cookies, and KeyPatrol, which detects keyloggers. Billing itself as the "Authority in Spyware Protection," it licensed its signature files for use in Yahoo! Companion, Stompsoft's Spyware X-terminator, Research Triangle Software's CryptoStick Software Suite and others.
Computer Associates (now CA) bought PestPatrol in 2004 and made it a part of its eTrust computer security line, which includes a virus scanner and a firewall. It was renamed CA Anti-Spyware in 2007.
