Hi,
about a week ago, I installed bitdefender security suite and I've been having problems with using Bittorrent. The download speed is reduced to one fifths of the maximum speed and is often measured in tens of kbs. I've already tried to forward the ports 6882-6889, to no use. I have btdna disabled. I disabled the whole firewall and realtime protection, with no use.
I use Windows XP and the version of Bitdefender is 2011 14.0.23.312
Thanks,
-K
