      I tried installing an extension for the first time and it said Error: An error occurred when installing the extension: Download interrupted with reason: FILE_SECURITY_CHECK_FAILED

          Do you have Windows Defender disabled and no other anti-virus enabled? If so, see https://forums.opera.com/topic/47516/interrupted-virus-scan-failed.

              @burnout426 No. I tried disabling that but it didn't change anything. I checked its log too and the last time it blocked something was in 2018.
              I don't have any other anti-virus enabled.

                Do a test in a standalone installation. Same problem there?

                Can you download other files?

                    @apaeter Just to be clear, you tried the registry change that I linked to? https://www.youtube.com/watch?v=kAARgC9zSJ0 shows a visual of what to do. Make sure you restart your computer too.

                    But, it sounds like Windows Defender is not fully turned on or something.

                      I am doing the test now and I did restart my computer when the problem first showed, and it didn't fix the error.
