Scan Antivir Defectueu

Bonjour,

Je vous explique mon problème : D'habitude , lorsque je fais un scan Antivir , il me trouve 1 fichier Warning . je sais que ce n'est pas un virus . Hors , hier il m'en à trouver 2 . je me suis dit que c'était bizarre . mais le problème , c'est que l'analyse est resté bloqué à 99.7 % ( ou à 99.4 % je ne sais plus exactement ) sur un fichier qu'il ne semblait pas vouloir analyser , puisqu'il est resté 40 mn sur le même ( j'ai noté le nom C:/WINDOWS/Installer/17c9ff4.msp ) . j'ai donc annulé le scan , et j'en ai relancer un . Pareil , 2 Warnings et encore bloquer pendant 40 mn sur ce fichier . je demande donc votre aide pour savoir si j'ai un virus , car je suis un peu ( beaucoup ? ) parano pour les virus , et je me sers énormément de mon pc pour jouer , donc sa m'embêterai vraiment de ne plus pouvoir .

j'ai malgré tout relevé et enregistrer le rapport de scan , je vous le poste , je pense qu'il sera utile . ( je peux également vous fournir un rapport Hijackthis si vous le souhaitez ) .

je vous donne le scan Antivir :
