...it's time to reach out to other antivirus companies.
If bitdefender won't come back...
reach out to panda. Great PUP detection, usually great malware detection rate too, panda by its self is worthless once it encounters an unknown file though. but that's why you would want to use it as one of the databases in SAP.
You could also reach out to immunet, which I found out a while ago is NOT the same database as Clam, even though they're both owned by the same company.
You also could reach out to Ad-aware, Vipre, Trend Micro or even reason security...which primarily focuses on PUPS and bloatware, but keeps actively distributed malware signatures in their database too.
Side note, you may want to label AVG as "AVG/Avast" the inner workings of those two programs are pretty much identical now and as far as I'm aware, they have the same database too.
