Macbook Air with Lion freezes during Time Machine backup...

I see a number of threads here with folks having stalling systems, but I have a situation where my Macbook Air completely freezes up (usually when Time Machine backup starts, or that's what I have observed when I wake the system up... the system wakes up, then freezes as Time Machine backup starts).

I logged a case with Apple and since they told me to remove Sophos Antivirus and since then my system has completely stabilized and I've not had a freeze in over a week (prior to uninstallation of Sophos my system was freezing up between 1 and 5 times a day).

Any ideas 'why' this is happening and if Sophos are aware of this and looking to patch/fix it?  Has anyone else experienced this issue and is it possible to run Sophos on Macbook Air/Lion or is there a compatibility issue?

Many thanks for any help/pointers!

    I have MacBook Pro with Lion OS. I had the same problem. Whenever the Time Machine starts, my Mac hangs. I tried to execlude some directories from Sophos but no luck.

    I finally solved the problem by disabling on-access scan from Sophos.

    I think sophos interupting the TM during backup process. Sphos should allow TM process to access all the files during backup without scanning.
