Avast slows down Vuze

Hello everyone,

Avast (premier) Firewall is slowing down my download speed with vuze by about half. If I disable the firewall it goes up in speed in a matter of seconds. Bittorrent and Deluge do not seem to have this issue. Also, If I try to run a speed test (inside the vuze client) or install a plugin, it will not connect at all. I only have Firewall installed, nothing else.
Os is win7 x64, vuze and avast are the latest versions, java is 1.8.0. I changed the rules for vuze and java to allow everying, but same issue.

What should I change?

  • Which version of Premier…?
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

Avast version is 17.5.2302.
I have no other security software installed.
No previous AV installed, just reinstalled the os (after format).
