How can i remove/repair win32.clspring!generic trojan?

Hi! i have been looking all over the internet on how can i repair this virus. I have found a few articles but none of them work, i saw one on this forum and i tried following it but i realized the files and processes taht wanted me to erase and kill weren't there at all...

My zonealarm antivirus detected it but failed to repair it... the file which has the infection is in
c:/Windows/System32/Rundl~1

I would appreciate ur help since my pc is almost new and it's performance has dramatically decreases I asume it may be because of this.

Thx in advance
