Unable to complete login after reboot

Hi,

I installed Sophos Anti-virus for Mac Home Edition yesterday.  Install went as expected.  I ran a custom scan on a small micro SD to try it out and it went well, so I ran a full system scan.  That went faster than expected - MUCH faster than ClamXav, so I thought, "I like this".  BUT!!!! When I went to restart my computer today, I was unable to login to my admin account.  The whole computer would hang and become completely unresponsive to any interface just after launching Finder.  I had to force shutdown using the manual button in the top right corner.  I then ran "Applejack", (which cleaned a HUGE cache file), and rebooted.  Same result, ie; hang after Finder launch.  Sooo, I forced shutdown again, rebooted in Safe mode, and uninstalled Sophos AV.  

It has been suggested on another forum that the problem is that my computer was not connected to the internet at the time I restarted.  My computer is a Macbook and I usually use it in a mobile environment, so I'm almost never connected to the internet when I reboot.

I like the product.  I've not had the slowdown issues I see posted here, in fact I was impressed by how fast it worked and how little CPU it used while running in the background, but until I can restart without problems, I'm afraid it will stay uninstalled.

FYI:  My computer is an '08 Macbook 13" aluminum with 4gb RAM, running OS X 10.6.4

  • I removed ProtectMac Antivirus, 

    installed Sophos Anti-Virus, proceed to restart, log in (as user with short name gjp22), etc. a few times. 
     
    Bugged twice. Both incidents required a forced restart. I didn't keep details of the first incident — the second incident felt more like the usual symptoms. 
     
    Files corrupted or lost during these incidents included: 
    • preferences for fseventer
    • preferences for iStat Menus
    • GoogleSoftwareUpdateAgent.log
    • preferences for various menu icons (AirPort, AppleScript, battery status, Input + Keyboard & Character, iSync status, Script, VPN and maybe other icons missing — and disorderly — following the second incident). 
    After logging a fair amount I uninstalled SAV, 
    installed ProtectMac Antivirus. 
     
    files relating to the second incident, which occurred around 
    2010-11-12 00:43 UK time. 
     
    I'm having trouble drafting this message (lithium again, heyho) so I'll post now before things become too jumbled then either edit this post or add a reply …

    • not relying on QUICKCHECK ONLY; FILESYSTEM CLEAN alone following forced restarts involving SAV, I routinely log in as a different administrator without FileVault then repair the .sparsebundle for user gjp22. 
    Errors in a FileVault .sparsebundle that contradict the FILESYSTEM CLEAN message are thankfully extremely rare, but in this second incident during a round of tests we're lucky/unlucky enough to find a minor block count error (in GoogleSoftwareUpdateAgent.log) that might correspond with either:
    1. the time that the computer stopped responding; or 
    2. the forced restart. 
    I vaguely recall a Google update-related file cropping up once before around SAV-related forced restart. I might find a bunch of relevant stuff in a ticket in the Request Tracker that I use.
