Business users have been notified (in advance) about the end of life. So yes, the virus definition updates for program versions 5 - 8 hav stopped.
The EoL has been postponed by three months (compared to what I mentioned) because of some delays on our side.
I see. Well, I never got notified. I'll try to migrate to 9.0.1506.
I just hope is not a problem or I will have to find a replacement.
In any case, thanks for your reply.
