Suddenly any program that runs is appearing on the ZA programs list & it's automatically giving some of them internet and server rights:
Windows NT Logon
Userinit Logon Application
etc., etc.

I've been using ZA for years and never had this happen with any other version before.

I've scanned my system with Spybot S&D, Ad-aware, Windows Defender, Ewido, Trojan Hunter, Avast, Housecall, Kaspersky's online scanner, Panda's Active Scan then the individual files that appear in ZA's programs list at Jotti and Virustotal. None of them found anything so I'm pretty sure I'm not infected or hijacked. Nothing unusual in HiJackThis log either.

Operating System:Windows XP Home Edition
