??? win32: gen. {autre} write in french please
What file is infected and where is that file located?
C:\Window\downloed Program Files\SysWebTelecomInt.dll
thank you for your aid
That file is part of the “SysWeb-Telecom Dialer File Malware”. Remove/delete it. Since a .dll does not run on its own, there are likely more harmfull files/processes on your system. Please post a HijackThis log here. You can download HijackThis from HERE
I don’t understand Hydjack, is an another program for virus ? : 
Hijackthis te montre presque tous les choses qui démarrent(“start”) sur ton PC et c’est ideal pour analysis/diagnose
