[NTSysADM] Sohpos disables UAC ?

[Klaus Hartnegg]

Has anybody recently seen Sophos Antivirus ("Endpoint Security") 
disabling User Account control in Windows 7?

Many computers here suddenly have UAC off, and my research points to 
Sophos installer/updater as culprit: UAC stays on when rebooting 
normally, but reproducably switches to off after a reboot that followed 
an install, uninstall, or larger update of Sophos. Maybe it only happens 
if SRP is turned on. I will continue testing on Monday, but maybe others 
already know more??

I had previouosly read complaints that antivirus software sometimes 
disables certain security features, but UAC!?!
