Symantec Protects Against First Known Trojan Horse for the Palm Operating System

Symantec's AntiVirus Solutions Protect Against Palm.Liberty.A

CUPERTINO, Calif. - Aug. 29, 2000 - Symantec Corp. (Nasdaq: SYMC) today announced that it protects against the first known Trojan horse for the Palm platform Palm.Liberty.A. This program was released as a patch for a Palm application called Liberty, but it was actually a malicious program that deletes applications from the Palm device.

"Norton AntiVirus detects Palm.Liberty.A on the desktop PC before the malicious application is synchronized to the Palm device," said Vincent Weafer, senior director of the Symantec AntiVirus Research Center (SARC). "Symantec is prepared to protect its customers against emerging malicious threats across a variety of platforms."

SARC does not have any confirmed reports of users being affected by this Trojan. However, if a user believes that his or her Palm device is infected, the user should set the Hot Sync manger to Desktop Overwrite Handheld. This procedure overwrites the infected files with the clean version on the desktop.

Symantec's Norton AntiVirus customers can download the current virus definition set, which includes protection for the Palm.Liberty.A Trojan horse through Symantec's LiveUpdate feature or from the Symantec Web site at www.symantec.com/avcenter/download.html.
