OS hangs on login

I recently installed Sophos Anti-Virus for Mac Home Edition on my 2011 MacBook Pro, however I had a major issue with it that forced me to uninstall it. I found that after rebooting, I would sign in and then the OS would hang indefinitely. My computer was unusable because I could not sign in. I was able to repro this condition at least 6 times in a row. I eventually had to boot into Safe Mode to uninstall the software and as soon as I did, I rebooted and the OS was back to normal operation. Are there any known issues with this hardware or any information I can gather to help diagnose the problem?

I get this problem too.
In fact I was having this problem in March, and eventually I realised that it was Sophos causing it. Today I tried Sophos again, and deliberately exercised it by logging out and in several times.
After several sucessful logins, I got a problem one in which one app failed to read the keychain on startup (this doesn't ever happen without Sophos), but the OS didn't hang.
On the next login the OS didn't hang.
On the next login the OS hung, requiring a forced reboot.
On the next login the OS hung again, requiring a forced reboot.
On the next login the OS hung again, requiring a forced reboot.
On the next login, the OS didn't hang, so I was able to uninstall Sophos.
I have captured by system.log file covering the period of the problem. What am I looking for? I'm quite happy to send it to you if you think it would help.
