Avira says that it has resolved the problems caused by a Service Pack that was released for its Windows products earlier this week. Users are advised to trigger a manual update to download the fix. Once installed, the update should prevent the program from blocking legitimate Windows applications on systems running Avira.

On Monday, Avira released "Service Pack 0" for all of its Windows products. Once the update was installed, the "ProActiv" behavioural monitoring component in Avira Antivirus Premium 2012 and Avira Internet Security 2012 blocked the execution of essential programs and trusted system processes. For example, ProActiv blocked the Windows registry editor (regedit.exe) and the task scheduler (taskeng.exe).

As the behaviour recognition is only included in the company's commercial products for 32-bit versions of Windows, the problem does not affect Avira Free Antivirus or users who run a 64-bit version of Windows.

Those who are affected by the problem need to update Avira manually; once the update has been installed, the ProActiv module can be reactivated. For systems where Windows is having difficulty booting, users are advised to start their systems in safe mode and install the Avira update.
