To solve this problem you have to do the following:
Open Avira Antivirus Configuration with Expert Mode. Go to General – Security and then uncheckProtect files and registry entries from manipulation. Click Apply and Ok.
Download the avreg.dll file (v. 10.03.00.08) From the respective Avira Antivirus website.
Go to C:Program FilesAviraAntiVir Desktop and replace the former avreg.dll file with new downloadedavreg.dll. You can also replace it here: C:Program Files (x86)AviraAntiVir Desktop).
Again open Avira Antivirus Configuration and check Protect files and registry entries from manipulation. Click Apply and Ok.
