Do you need to use a proxy server in order to access the internet?

ais 5.1.864

Try this build: http://files.avast.com/files/beta/5.1.884/setup_ais.exe

Better to try the new Official release 5.1.889, you should be able to get it from the avastUI doing a manual program update. See http://forum.avast.com/index.php?topic=69305.0.

Edit: wrong build number (typo).
