Trojan.ZeroAccess!kmem BIG PROBLEM

Hi,

 

i'm having problems with this virus, i read all the post realted to it, but couldn't remove it. I don't know too much about this, so it's dificult for me to understand all the posts.

I run the removal tool, it said that it removed the virus, but it didin't. I also run the Power Eraser, it removed some other files, including this trojan, but then , when running a scan, it detected on windows/system32 as a fil name NTOS. The action is LOG ONLY and the file is left unchanged, what can i do?

 

Sorry for my english.
