Comment enlever un cheval de troie

Bonjour Marie ,
je te remercie de m'avoir répondu aussi vite et simplement , j'ai donc suivi tes conseils et voilà le rapport que je ne comprends pas bien-sûr , pourrais-tu m'éclairer sur le résultat et me dire si le virus est encore là ou non. Je t'ai déjà envoyé un message mais je ne suis pas sûr qu'il est fonctionné .
Et encore merci!!
Sans oublier de remercier BUBU24 ET BRUCE
