1663283232381.pngThat shows up on my Windows Defender. I reset my Acer laptop to factory not because of it but once back up & running correct, it was gone, now its back. I think it has to do with a USB EXt thing that has ports for more, I'm confused

Open File Explorer, then navigate to C:\Windows\System32

Search for usb2ser.sys

Then right click the version of that driver that was found in the Drivers folder and select Rename, and rename that file to usb2ser.sys.old

Then restart your PC and that will stop that driver loading. Found that here https://answers.microsoft.com/en-us...b2sersys/cd395ce7-ff6e-4bc0-a702-93ac048aff9c
I'm not on 7, I'm on W11 Home

If you have any difficulty renaming that file, boot into Safe Mode and rename it from there.
