Thats dealing with AV software on Windows but as said Windows and Linux same behavior and non AV software or firewall on my Linux. Downloads from Renderosity as also Posersoftware are starting with at best 125kb/s and then going down to at least 7100b/s and the above named broke completely down at 289 of 295 MB and is not resumable. So this is not a problem on my side cause all was running well 2-3 weeks ago and here nothing has changed. Its a (new) problem on serverside at Bondware.

But thanks for your assistence but not according to my problem. Will wait if the diagnostics report on Renderosity will give answers.
