Sophos Anti-Virus for Mac V7.3.1 is compatible with Mac OS X Lion

Definitely worth testing; this doesn't seem to show up in all configurations, so the more edge cases we can explore, the better.

I am having trouble with the scan stopping but indicating that it is still running when I try to close and reinitialize.  Any thoughts?

So far so good...

I tested it for a while and the result is that I will keep it working like this. Which means:

I disabled all the external discs from scanning. I only allowed one external partition to be scanned but NOT time Machine.

My mac seems to stay stable and it seems no more maxing out of CPU, is happening. I will come back to report if it stays this way or if it goes crazy again.

Excellent news!  So you're saying that you are and were not using network shares, but were scanning all locally attached media, and that excluding your Time Machine drive fixed the CPU error?

When you say "scan stopping," do you mean that you get an alert saying that the scan has stopped unexpectedly, or do you just mean that you see no progress in the scanning progress bar?

And when you say "close and reinitialize" are you talking about manually stopping the scan and restarting it, quitting Sophos Anti-Virus and then re-launching and starting a manual scan, or turning on-access scanning off and back on?

I did use a network share, that I now excluded. I did also use Time Machine,which I now excluded. The only spike I saw so far was when Sophos updated from 7.3.1 to 7.3.2 but only DURING the update. After that it returned to normal behavior. I have one local disc attached that is included in the Sophos scan. But it is not giving any problems anymore.

Yesterday I did a re-install of 10.7. Due to widespread reports of computers crashing for no obvious reasons. (see http://goo.gl/ewcLd )

I thought maybe a re-install could help. After the re-install the settings of Sophos remained the same. Yet Sophos, Time Machine and Spotlight were each fighting for the CPU. So after all I think the settings of Sophos do not matter so much. I had do uninstall Sophos, stop Time Machine and wait for Spotlight to work itself through all the files. When Spotlight calmed down I enabled Time Machine. It took an awful lot of time and processor attention to complete it's 'first' backup. When TM was finished I re-installed Sophos again. Maybe it would have been enough to disable it. But after doing that I still saw intercheck going nuts on the processor. So I removed Sophos temporarily.

Now everything seems to be normal. I don't know if my black-screen bug is gone..........

But maybe you should advice ppl to disable Sophos when they install new system software.

Immediately noticed a problem with Intercheck, specifically it takes 115MB memory which forces paging out .  Intercheck utilizes the largest chunck of memory and holds it even when it is not running.  Would reccomend SAV 7.3.1 only with a memory upgrade.
