OK, I'm tired of this.
The virus signatures for 4.8 didn't stop because there are still to many programs being used (e.g. the business editions of avast!, and also older editions of g-data), so it's simply not possible to terminate the support, no matter how much we'd like to do that.
As for the g-data engine, you are simply wrong, it has been updated quite some time ago.
Done, please go accusing people of lying somewhere else.
