I got that stupid virus that pretends it a screensaver. But, none of the yaha tools are working! It diabled Norton, and my Task Manager! I found a file called nav32_loader.exe, which is preventing anti-virus to load. I deleted it, but it comes back!!!

Hello Drew, Of course its comes back, it will come back as long as you don't destroy the "worm" installed now somewhere in your hard drive... waiting to be connected to internet to call the creator of that trojan virus in order to give him the hand of your computer... if he is connected at the same time than you. I recommend you download a program especially made to hunt for the betrayal's trojan corruption, very easy to use, freeware for a month: Trojan Remover 4.95 The only trojan program to repair totally a computer from the 6343 athentic's trojans sigantures reconized by the database, including the 3 Yaha's variants. Try it and you will be save: Trojan Remover 4.95 at: http://www.simplysup.com/tremover/details.html Good luck and Happy New Year

Don't waste your time on these so called trojan hunters..they do nothing..i used trojan hunter,trojan cleaned,tauscan,and some others..and they are pure crap...if you want something good and i mean REALLY good..get kaspersky AVP(anti virus personal),the best you can get..hunts all the viruses and trojans...or you can get a small utility specially for this yaha...at http://www.bitdefender.com/html/free_tools.php

Drew this works...ran it once and it got rid http://securityresponse.symantec.com/avcenter/venc/data/w32.yaha.k@mm.html

Hello Adiel, When you don't know nothing, better to shut your mouth... Karpersky is in fact a very good and excellent product, but very expensive too, and to have a good configuration with it, you need already at least a medium range experience about computers. You have to know that 99% of people coming here don't have any idea about what is a virus and less about a trojan virus... That's why a program like Trojan Remover (not Trojan Hunter), is wonderful to help people to clean a computer from the long story of Virus Betrayal...

Hey Imp, You appear to be the one who doesn't know what he is talking about. Yaha is NOT a trojan. It is an executable program. (a worm) And it DOES NOT do this: "Of course its comes back, it will come back as long as you don't destroy the "worm" installed now somewhere in your hard drive... waiting to be connected to internet to call the creator of that trojan virus in order to give him the hand of your computer... if he is connected at the same time than you."
