Right now, the recommendation is given according to the virus type and source it came from (file, mail, ...)
So, VRDB is not consulted before the Virus Dialog is shown. I'm still considering changing it... of course, the results would be better and the users will be less confused if the Repair button was shown really only when the file has a VRDB record. The problem (in my opinion) is that initialization of VRDB may take some time (seconds) - so the Virus Dialog would be delayed...
