I have installed FDM 3.9.2 build 1303. It contains FDM plugin version 1.5.7.9 with Maxversion set to 21(I modified to 30). I've done the routine specified in " http://www.freedownloadmanager.org/board/viewtopic.php?f=1&t=11665#p36150". While FDM works with Firefox 21, it does not work ...

BitDefender has quarantined "fdmumsp.dll" with "Trojan.Heur.LP.fu4@aGwzv0jk". Is there a chance it is infected?

Thanks,
Grouch
