TR/Dropper.Gen

Bonjour à tous les Membres !

Mon antivirus Antivir (version gratuite) a détecté à deux reprises en moins de 5 mn : TR/Dropper.Gen

le premier : acces denied (j'ai fais)
le deuxième : mise en quarantaine (j'ai fais aussi...)

Pourriez vous me dire si tout danger est écarté ?

Je vous fais une copie du rapport Hitjckthis. Si vous avez besoin d'autre chose, je reste à votre entière et totale disposition... Par avance, merci !
