@lexisuperman What's the exact path where it finds that file? I don't have that file and don't know what it is.
Would be good to goto the URL opera://about, take note of the "install" path, close Opera and uninstall Opera (but don't choose to delete your data when uninstalling, unless you don't mind starting over). (Before you do that though, it might be good to goto the URLs opera://mods and opera://extensions and remove all your mods and extensions.)
Then, delete the install folder as it will be left behind with a few things in it.
Then, delete everything in "C:\Windows\temp" and "C:\Users\yourusername\AppData\Local\temp".
Then, download Opera GX from https://www.opera.com/download#opera-gx in another browser (Edge for example), launch the installer, click "options", uncheck "import data from default browser", adjust all the other options as you like and install.
Would be good to scan your system specifically with the free version of Malwarebytes too.
Would be good to upload the exe to https://www.virustotal.com/gui/home/upload too to see if it's just one or too silly heuristic detections that flag it as a trojan or if a whole bunch of engines do.
