Having installed BitDefender 2010 & got around the corruption issues and turned off all the services that make it un-usable (ie vulnerbility check, antiphishing and limited auto update due to Vsserv.exe issue) I have now had to turn off the Anti spam as it blocks all my 'good' email but leaves some spam!!
I thought this was due to my old learning store, so I wiped that, still bad, so I turned it to minimum, still no better.
It will classify perfectly good email as spam, then refuse to change its mind!!, Ie I say 'not spam' and add sender to 'friend' list, yet despite this it will send the next message from same sender strait to spam, seems spammer list overides friends list, so i have to manually delete my friend from the spammers list for every new message.
As this is totally useless, I don't want to just see spam in my inbox & have to go to deleted to see all my 'real' mail, marked spam!!
Is this part going to be fixed, or have you no 'real' programmers working for you anymore!! 
PS I`ve had to set autoupdate to once per 24hrs due to Vsserv.exe issue that you also seem to be stuck on, but why does it ignore that setting & update every few hours still!!
