Computer won't boot after using Defender offline

Lets see something. Right click on Firefox select Properties . Inside the Properties window click on the Shortcut tab inside the Target section it should say only this "C:\Program Files\Mozilla Firefox\firefox.exe" if it has anything after that delete everything after Firefox.exe .

You have a 64-bit OS . On 64 bit OSes you will have two C:\Program Files folders one will be C:\Program Files for 64 bit software and the other will be C:\Program Files (x86) for 32-bit software. Firefox is a 32bit software so it installs in the 32 bit Programs Folder .

Ok lets download a new copy of FRST64 .
