Another new problem with Sygate and Web Shield, after some time of surfing, whenever I open up multiple browsers, web shield would crash and I have to restart the system to get it working again. For example after running Opera, I would also open up Firefox and within minutes, webshield would crash and pop up with an option of sending error report. I tried terminating as well as pausing and restarting webshield from Avast control panel but no go, system has to be restarted to get it working again.
This phenomenon does not happen in case I am using other firewalls like Jetico, Kerio, ZA etc.
An update, after updating to beta 4.6.635, the problem seems to have gone away. Nice work Avast, Could not find another free ICS supporting and stable firewall like Sygate but was not willing to give up on Avast as well, was in a real dilemma.
