You need to download ComboFix, save it to your desktop. Boot in Safe Mode with Networking.
You can download it from the link below.
After you have booted in Safe Mode with Networking. Then run Combofix. You probably won’t be able to run it in normal mode with the Fake Alert running.
It says that link is expired. It has another link but now I’m concerned if it’s legit. I so appreciate your help..would you mind taking a look at the link and see if it tells you that too?
