Same problem here. Disabling the Web Anti-Virus component seems to have worked. Windows 7 computers did not experience the problem. I cannot believe that we left AVG for this. Nothing but problems. First a wonderful 50/50 chance of successful install/deployment, then Network Attack Blocker and now this. Wow. I'd rather have the home user version of Kaspersky on our machines here instead of the bloat that is KES. Well done.
