hi atulsaxena,
Have you checked to see if you have this file on your system?
Microsoft Visual C++ 2008 Redistributable Package. File path should be Program Files((86x) if Vista or higher 64-bit)>Common Files>Microsoft Shared>VC>msdia90.dll. Installed version should be 9.0.30729.6161.
If not, you need to install it for avast! to work properly. See attached .jpg below for file path on Win 7 Home Professional. You did not say what operating system you are running, but file locations should be similar. If search does not show anything, then you are missing this critical install; version you need will depend on your operating system.
Reason I say this is because you just formatted and installed a fresh, clean operating system from scratch few days ago. As such, you likely are missing other needed drivers as well.
