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 Suiteand 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.
The program can be bought separately, or as part of CA Internet Security. Although it could be obtained for free on pirated pages, the risk of malware increases.
