Error Application module cannot be found

Hey,
I am getting this error message on and off in the computer. I get this error mostly when I start the computer, after a while when I run quick scan, it works fine. This error is not creating any problem, but it is very annoying. How to stop this error from popping? I tried to uninstall and reinstall the antivirus but nothing worked. Please help. Thanks.

The application module
C:Program FilesAviraAntiVirPersonalEditing Premiumrcimage.dll
cannot be found or has been modified or destroyed.
The AVWSC.EXE cannot be started.
Please check your installation!
