I scanned the drives for errors and repaired avast too, but nothing happened.
After a few restarts now it is behaving normal. But I am sure from these experiences this will happen again soon.

I will be thankful to all for the help.

Thank you.

Do you have any other antivirus installed in your system?  Did you have in the past?
Any other security programs that could interfere?
Is there any useful information into Control Panel > Administrative Tools > Events, specially 'Errors'?

Can you try to repair your installation?
Go to Control Panel > Add/Remove programs > avast! antivirus > Remove. Then choose Repair function in the popup window (Repair).
If this does not help, can you uninstall / boot / install / boot again?

What version of Avast are you using? I had same issue with 1282 however
1290 sorted it out.
