Trojan-Downloader.Win32.VB.bbl

[Hakon]

I found this awesome virus "Trojan-Downloader.Win32.VB.bbl" and analyzed its behaviour in a VirtualBox and quickly found a weaknes
It is very hard to remove, it closes antivirus setups and then deletes them, closes all windows containg anything about antivirus tools (even if you google anything about it, it closes your browser)... AND it starts up in safemode too!
This post is only to ask for your opinion, a little bat file i created to remove it (and it works!).

@echo off
setlocal enabledelayedexpansion

cd %windir%\system32
if not exist "%windir%\system32\wins.exe" goto nothing:

set /a counter=!counter!+1

:start
cls
echo Try %counter%

if %counter%==5 goto fail

if not exist %windir%\system32\wins.exe goto done

:done
echo Done!
pause
exit

:nothing
echo You are not infected by LeChucK.exe
set /p choice=Would you like to clean the system anyways (Y/N)?
goto %choice%

:fail
echo Failed to remove LeChucK.exe 5 times, contact tech support :[
pause

:n
:no
exit

Edit:
I have the virus if anyone is interested in testing, but im not sure how...upload it or sumthing?

 

[kirov]

upload it in an encrypted archive in an encrypted archive in an encrypted archive that each have different 31 character hex-decimal passwords that you provide

that should provide the rest of us enough protection
btw, what malicious activities does this virus conduct?

 

[Hakon]

Its supposed to download more malware! but i havent seen any of that yet...

 

[kirov]

can you upload it? I'm interested in testing
