Cheval de troie : win32: Purityscan-S[Trj]

Bonjour !!!

A l'aide ! A l'aide !

Avast m'a détecté un cheval de troie qu'il a appelé : win32: Purityscan-S[Trj] et win32:Ndrv [adw]

J'ai essayé plein de logiciels différents, dont bitdefender, ewido et ccleaner, comme j'ai pu le lire dans divers forums, mais ça revient toujours !! Merci bcp par avance
