hi, "FirefoxUpdate.exe" as it appears in that screenshot is not a genuine filename that is used by mozilla as far as i know! it looks like thrid-party malware hooking into firefox.

next to the security software already in place, please run a scan with various other security tools like the free version of malwarebytes, adwcleaner & eset online one-time scanner.

then please manually delete the whole c:\program files (x86)\mozilla firefox folder and reinstall the browser from https://www.mozilla.org/en-US/firefox/all/

Nothing resolved, he tells me it's virus only as I download it I agree to download even if it signals it as a virus, install it, and after some time the antivirus automatically deletes it, and when I click on mozilla tells me that the file does not exist or it was deleted, this signalizes me To restart on pc

What is the security software you are using. You should contact them to ask if this is a false positive. Please give the full name and version of the security software and its support site. If they have a public support forum please report the problem the and let us have the link of the report.

Note this is a useful site to check

Are you using the full installer or a stub? Did you use the link I posted above?

I use Panda Protection antivirus, I uninstalled and mozilla downloaded it again from a link I received on this topic. After installation, the virus detected the FirefoxUpdate.exe file again as a virus but this time, mozilla is working normally, Excuse me for writing, but it's not my original language

Nu s-a rezolvat problema Fred.. acum 10 minute.. 15 maxim, mi-a semnalizat mai multe fisiere ale mozilla ca fiind niste virusi, si acum nu mai functioneaza deloc mozilla, Am apasat pe shortcut si imi zice fisier dezinstalat sau inezistent, initial am avut ca antivirus windows defender.. care .. acum 6 luni mi-a expirat licenta.. dar totusi imi spunea ca pot beneficia in continuare de scanare dar inafara de unele care se pot face doar pe varianta platita, si timp de 4-5 luni imi tot zicea ca nu gaseste nici-un virus, si m-am gandit ca e ciudat.. si am incercat prin alt antivirus respectiv panda antivirus, acesta imi semnalizeaza ca virus mozilla..

Se pare ca de atunci nu am mai avut nici-o problema legata de firefox, am facut o scanare prin adwclear si a gasit peste 120 de fisiere infectate printre care erau unele si cu numele firefox si ceva adaugat pe langa nume, acum pare ca totul s-a rezolvat va multumesc mult pentru tot

It seems that since then I have not had a problem with firefox, I did an adwclear scan and found over 120 infected files, some of them with the name firefox and something added to the name, it now seems like everything I've been happy to thank you for everything
