Hi, @Pilot-Luke. This looks very similar to this thread: After updating Tor to 11.0.9 my Antivirus told me: libEGL.dll is infected. See Screenshots. I had to delete this file
Please check whether your antivirus is flagging this for some another software on your machine.
As far as Tor Browser is concerned, if you ensure it’s downloaded from the website (for 32-bit and other locales) and verify the signature in order to ensure the file has not been tampered with, you have nothing to worry about.
