To disable Avast you must open Avast User Interface by clicking on system tray icon to Avast...When Avast User Interface has loaded, go to REAL-TIME SHIELDS and turn them off one by one and only disable them for about 10 min max at the time for every shield...They will automatic be turned on again after 10 min expired! Btw Avast usely is a good Antivirus software that works great with P2P software because of it's buildt in P2P Shield...
