full system scan hangs

I installed the new CAV V3 … here is the info:

product version 3.5.54375.427
virus signautre database version 549

Everytime I run the system scan from the Antivirus, it never completes itself and hangs on the way.

I searched few posts in the forum, and got a reply saying its fixed in the latest release. I have downloaded and installed the latest release around 6th nov only… that is the lastest avaliable on the website.

still the problem is not fixed yet. please help.
