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

Anonymous

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.

Afraid it has not worked for me.

I cannot find UBCD4Win, anywhere listed on my computer.

Press Windows key + R

Type: msconfig

Hit Enter

Go to the Services tab

Check the box 'Hide all Microsoft Services'

Look for any entries for Avira and uncheck them.

If that does not work, open the C:\ drive then open Programs files

Search for Avira then delete any such folders.

You can also try upgrading using the ISO file.

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!

Deleting all of UBCD4WIN seems to have fixed mine as well. Many thanks. It was an annoyance.
