Okay here's the deal:
Since I switched to avast!, I have some really mean ping problems and also disconnects in Warcraft 3. It's got nothing to do with my Internet as far as I can tell, because I'm often in a Skype conference while playing and the conference just keeps running on normally while I first start to lag a little bit and get increased delay, and all of a sudden I just disconnect from the Battle.net. This also happens when I'm just in a chat channel when there's no big package exchange or anything.
The following ports should be open @wc3 to prevent lag/delay problems and to be able to host a game: TCP 6112 - 6116.
They're all open ever since and I never ever had any problems with sudden delay increase or disconnects up til the day I installed avast ... :C
Any ideas?
heres my specs:
Core 2 Duo E8200
NVidia GeF8800 GTS 512
4GB Ram
Windows Vista Home Premium 32Bit
