Everything, Everything

I'm not sure why, but after turning my computer back on (I had set it to hibernate), Windows pointed out that my anti virus software wasn't working. So I checked Sophos, and the service had indeed stopped. When opening the main interface it told me and the service was restarted, but the Windows Security Alert won't go away. Also, the "Turn on now" button is disabled, presumably because Sophos don't have a mechanism for starting it up that way. Seeing as this one has been around for a while (since XP SP2 came out in August 2004?), I'm again surprised that Sophos bitched so much about access to APIs and can't manage to write something as simple as this. In the end I had to run services.msc and restart the "Sophos Anti-Virus status reporter" service to make the little red shield go away. I still don't know why the service had stopped, but I now have AVG and Microsoft OneCare setup files, and will give them a try the next time something goes wrong. Anti Virus software shouldn't cause processes (msfeedsync with NOD32) to die with DEP errors, or have their services (Sophos) randomly stop. I'll give Sophos the benefit of the doubt for now, but the last thing I want is AV software that stops working for no good reason.
