Hi All,

I managed to solve this antivirus removal and bluescreen issue. I downloaded the avast removal utility @ http://www.avast.com/uninstall-utility
Then I run that utility as it boots into safe mode. After that It helps me to remove the whole avast files/registry in my computer.

After the antivirus removal, I was able to reinstall the new avast version at normal boot up.

Thanks to the utility.

:wink:
