Problem while performing full system scan with Avira

until Sep 2012, I did not encounter any issues while using Avira - Free Version, for a complete system scan. I have an habit of scanning entire system once or twice a month.

Since, first week of October or late Sep.. I have been having issues with Avira when I initiate a full system scan.

The scan stops at 18.1% - it just blinks over there.. as if software is shivering out of cold.

Used Time - works properly
nothing else changes.

It stops exactly at :
C:\ProgramData\{some random numbers and alphabets}\mia.lib

It gets stuck even when I try to cancel the scan, I am usually rebooting to get over this mess.

I tried Malware Bytes scan.. it didn't give me any errors.

Just in case needed, I have W7 with 2GB RAM, 500GB HDD - Dell Laptop

I would like to have suggestions on what I can do ? Do I need to switch AV or any configuration changes I have to make to my system ?

help would be appreciated.

Don't know if this will help or not but it may. Avira may have become damaged or corrupt for some unknown reason so it may help to uninstall your current version and reinstall a clean copy. If for some reason you can't uninstall from control panel > programs and features, follow the instructions in this Avira article:

Instructions for manual uninstallation

Once the product has been uninstalled you can reinstall fresh copy.
