Initially unsure of the best place for this thread, just move it if needed. It came up while browsing user or local app data on the C: drive, showing a "Chromium" folder. Since you haven’t installed Chromium and don’t recognize its source, it’s not immediately concerning. The antivirus report says everything looks normal, so it doesn’t seem like a virus at this time.
Avoid removing folders you're unsure about, as they might be needed by other software. If you didn't install Chromium, another program likely took its place, and deleting the folder could cause issues. You can rename the folder to something like "_Chromium" or similar, then keep it unchanged until you confirm everything works. If no programs stop functioning, it's safe to delete it.
