I downloaded an utility software and tried to install it. Even that I didn't finish the whole installation but my PC is infected by it.
And then wierd thing happed!!
Sound device is dead. Windows update is dead.
I can not install any antivirus software.
I tried to install Kaspersky 2010 but failed and KAV 2010 said the failure reason is my PC is infected .
The malicious software i download is "Directory Eraser" from here.
Virus Total scan report confirm it's nasty. (VirTool.Win32.VB.ek)
Please help me. Thanks in advance.
