Windows 10 update asks to uninstall Avira AntiVir (which I don't have)

Hello everyone,

a few days ago I tried to update my Windows 10 installation. My computer tried many times to upgrade the OS, but after the first reboot, it was keeping rebooting constantly, and after the 4th reboot Windows automatically recovered the previous state, saying that the upgrade failed.

Googling for a solution, I have found out that a bug in the updater affected several thousands of devices, and I have installed the bugfix from the knowledge base.

Now, there is an additional issue bothering my Windows. When I start the upgrade procedure, it asks to uninstall Avira AntiVir because it's not compatible with the upgrade. I would do that, but I have never installed Avira AntiVir in my life. I tried to search in the disk and in the registry with the keywords "Avira" and "AntiVir", but I don't get any result. Indeed, I have never downloaded not even the installer of that software.

The upgrade can't proceed, the only thing I can do is to cancel it.

Any suggestions?

Thanks

Solved (for me):  I had the same issue, the Win 10 install/upgrade kept asking me to manually uninstall "Avira", and another item "BDrom driver".  Like Francesco Di Caprio, I had never installed Avira AntiVir, nor was there any evidence of that in the registry nor on my hard drive after doing a thorough search. Earlier in the installation process Windows asked me to uninstall UBCD4Win, which appears to have arrived preinstalled with the Dell computer. I unistalled that using the control panel. After uninstalling that, (now a second attempt to install Win-10) I started getting the repeated warnings about "Avira". I did a registry search and a file search for "Avira". Nothing.  I did a registry search for UBCD4Win and removed all entries containing that. There was LOTS of UBCD4Win stuff remaining that the uninstaller did not uninstall.  Also did a search on the hard drive, there was a subdirectory with tons of UBCD4Win utilities. I deleted all UBCD4Win directories and subdirectories.  Why lingering UBCD4Win files or registry entries trigger a warning about "Avira" is a mystery, it seems unconnected, but apparently it does.  Then I restarted the WIN-10 upgrade (third attempt). It worked.

    Thanks for this tip. It solved my problem.  I was having the Avira uninstall problem on my 6 year old computer which MS actually fixed at their 3 level support.  All the support people where nice and professional that I worked with.

    I purchased a new computer and used laplink to move most of my old programs over from the old computer to the new.  When I went

    to upgrade to the new 1803 windows release I got the Avira uninstall error again.

    Did a search for "USCD4Win"  found it with an uninstall USCD4Win.  Did the uninstall and windows 1803 completed the installation with no problems.

    I didn't find the folder -  "HKEY_LOCAL_MACHINE/Software/Microsoft/WindowsNT/CurrentVersion/AppCompatFlags/UpgradeMigration"

    I couldn't find anything related to UBCD4Win

    So, I'm still stuck.

    Afraid it has not worked for me.

    I cannot find UBCD4Win, anywhere listed on my computer.

    I was getting the same errors on a completely clean install of Windows 10 using an ISO downloaded directly from Microsoft using the Media Creation Tool, so obviously it never had Avira OR UBCD installed. Checking that registry location showed me that the upgrade was complaining about some old installer files for a Linux emulator that I had saved on a secondary external hard drive that happened to be plugged in to the computer at the time I was trying to install Windows updates. I unplugged the external drive and Windows Update stopped complaining.

    Thank you for the excellent suggestion!
