I have a client machine here that was brought in because sophos started to fail on updating. According to the student who brought it in, sophos was running happily for quite some time, and then simply started getting a failed update notification. About three different work-study techs looked at this before it landed on my desk. Some of the things they checked were to run several virus/malware/rootkit scanning utilities to ensure the system was virus-free, Checked that no other AV programs remained, ran system file checker to ensure that windows files were all intact, and did a complete uninstall of Sophos including post-uninstall scrubbing of the registry of all Sophos entries, deleting any remaining sophos files from windows/temp, program files\sophoos, and all users\application data\sophos\ .
As it stands now, it appears that when sophos installs, it only installs the auto-updater, and then fails. When it gets to the screen that says "Installing Sophos antivirus for windows --Installing package 1 of 2", that takes a bit, and then immediately following the "package 1 of 2" step, the window closes out and the icon shows "Updating - Failed" with a red X on the shield.
When right-clicking the notifier in the system tray, the option to open sophos endpoint security and control is greyed out, and subsequently choosing update sophos results in a repeat of the above.
After the failed intall, the following services have been started according to the windows services utilty:
Sophos Agent
Sophos AutoUpdate Service
Sophos Message Router
LOG:
From the program installation directory, autoupdate/logs, is the update log, which i loaded into pastebin: http://pastebin.com/pP4jFQ9Z
The system is running Windows XP Home Edition sp3
I hope i've given enough information to get this started. I've turned on email notifications for this thread so I'll be right on top of things to add more information, etc, throughout the day.
Thanks in advance,
