I also have this problem with bmail.exe, it just started over the weekend (with the 080112 update).
I don't have a problem with adding bmail.exe to my exclusions lists, but it doesn't work.
I was able to add the exclusion to both places mentioned, but the on-access one is ignored. Whenever I try to run bmail.exe it flags as a virus. Right-click in explorer and select 'scan' and it replies as expected, that 0 files were scanned and 0 viruses found. But the on-access method just doesn't appear to be working, I probably have something setup wrong because when I go into standard shield and try to move the slider to 'custom', it goes back to 'normal' after I hit OK and re-open the standard shield settings. Sorry to sound like a newbie, but I'm cold and tired, and hoping this sounds familiar to somebody that quickly reply with some idea of why my exclusions are ignored.
Thanks,
Craig
