Hi. WARNING !!!! KHATRA.EXE is a VIRUS!!

I HIGHLY reccomend that you go to microsoft's website, and download microsoft security essentials.

This is a highly efficient anti-virus/anti-spyware, and anti-malware program, that not only will keep your computer clean, it will provide real time protection against all known threats!


Khatra.exe is actually part of a group of files that will be located in the located in the windows/system32 directory

Khatra.exe, gHost.exe, and xplorer.exe

Here is the solution on how to remove them

Download this program, it is called Stopzilla, and it will clean and disinfect your entire system.

Here is a link for the program: http://www.virusremovalguru.com/software/stop.php

It is really good for this type of viruses.

It also will not conflict with microsoft security essentials, so you will have anit-spyware and anit-virus that can run independent scans at the same time!

I hope this helps.

If you cannot access the internet, due to the infection, use someone elses computer, download the files for both programs, and burn them onto a cd, this way you will also have an emergency rescue type disk, should this happen again.

for windows 7 avast compatability have been released just try tat

Run your PC in safe mode with networking prompt as an administrator(because in normal mode the virus will not allow/let you to run a setup file if it's a dangerous virus).Install strong anti-virus like Kaspersky, NOD32 etc. registered version. Update the anti-virus in safe mode and also run.

I think it will help you.

Good Luck

--- please first of all arrange system setup disk for WinXp
--- Start Windows in safe mode, if yu can, uninstall all undesirable programs, antiviruses, TSRs
--- Restart System
if problem is not solved, please repair windows, by setup & upgrade from the XP installation disk.

Spyware Doctor, Panda are good antiviruses, please update them on internet after first instalation
