Avira flags Windows Store as Virus and blocks it
There is no way to ignore this or add the affected dll as an exception to Avira as Windows 10 doesn’t allows to access contents in the WindowsApps directory.
Avira asks to update Avira desktop and starts to download files when you accept (this happens in a loop every time when you start your computer, to avoid this, turn off real-time protection for Avira), but the damage has been already done, if you try to launch Windows Store, it just crashes.
