Le log Avast!4 sur le virus Trojan Gen:

11.02.2008 15:28:35 1202740115 Vegeta 2008 Sign of "Win32:Trojan-gen {Other}" has been found in "E:\Star Wars Knights of the Old Republic (rar)\Star Wars Knights of the Old Republic CD 1 of 4\autorun.exe" file.

J'ai efffacer le premier fichier mais pas le deuxième.

J'ai fait des scans de AVG Anti-Spyware,Ad-Aware 2007,Avast,Etc... rien y fait toujours cet lenteur.


La je défragmente le disque.
