I recently had the problem of my SAV not updating anymore (probably the generic one discussed here – but in addition, On-Access scanning was also disabled and I couldn't switch it on anymore). I resolved this by uninstalling and re-installing SAV. Now the updates essentially work, and so does On-Access scan, BUT:
Whenever I've just restarted my computer and logged in, and have a look at my SAV settings, I find that the settings are not protected anymore (it reads "click the lock to prevent changes"), even though I always, always, always protect my settings (such that it should read "click the lock to make changes"). (Also, once I noticed the Sophos logo in the toolbar suddenly going from black to grey, as if it were turned off, but as soon as I clicked on it, it was back to black and everything looked normal.)
Now I really worry, is there some malware meddling with my SAV?
