My Windows virus protection shows nothing but I keep getting notices int he lower right corner of my screen that say Mozilla Firefox ESR and tell me there is an infection. It tries to take me to a website to scan and then buy McAfee to fix it. If I make sure Firefox is shut down (forced through Task Manager) it seems to go away. It appears that only the Firefox browser may be infected.
