[Virus] Win32

Bonjour, ça fait quelques temps que j'ai des problèmes avec des virus ... j'essaie d'erradiquer mais ça revient ...
De mémoire c'est toujours (nefin ce que j'ai trouvé) des virus de type Win32: ...
Pouvez vous m'aider ? pour ce qui est de winpcap, c'est moi qui l'ai instalé pour utiliser wireshark histoire d'essayer de comprendre ce qui se passe ... est ce que ça présente un risque ?
Merci
