I recently ran Emsisoft A squared (A2) Scanner and it came back with the detection of a trojan in Zone Alarm files.
I have ZoneAlarm Security Suite 9.3.037.000, TrueVector security engine 9.3.037.000, driver version 9.1.522.000, Anti virus/ Antispyware engine 220.127.116.11 DAT file version 1044470464, AntiSpam version 18.104.22.1683).
The report was:
C:\WINDOWS\system32\ZoneLabs\avsys\bases\pbs.kdl - detected: Trojan.SuspectCRC!IK
C:\WINDOWS\system32\ZoneLabs\avsys\temp\temporaryF older\bases\av\kdb\i386\win\pbs.kdl - detected: Trojan.SuspectCRC!IK
www.virustotal.com also reports this, but then again only by the EmsiSoft and Ikarus scanners. It might be a false positive, but thought it good to report here...
PS... ZASS itself has not reported this Trojan
