Hi,

Methods to restore .exe functionality AFTER removing the malware.

1. Make a Restore Point so you can revert back if needed though not likely required.

Answer
Hi,

Try Safe Mode with networking - repeatedly tap F8 as you boot up.

The top two methods allow the scanners to run and/or get AV.exe out of the way or removal.

1.
CTRL SHIFT ESC  - Task Manager  OR Right Click the TaskBar - Task Manager

Processes tab - End Process on AV.EXE and then proceed with the Uninstall Guide.

If needed use Start - Computer  OR  Windows Explorer  to navigate to

C:\Program Files\Malwarebytes' Anti-Malware\mbam.exe  or where ever it is installed at - if
needed Right Click the Malwarebytes - Properties - Shortcut tab - target line to see where it
is installed.

Right Click on it and Rename it to ZZMbam.COM (or anything different than it is now) and
then double click on it and run it that way. You can rename it back later. Do similar with
other programs as needed. Use this method for others as needed - DO NOT ASSUME any
one program removes it all or that there is not other malware involved. Use the .COM
extension as this malware prevents .EXE from running.

---------------------------------------------------

2.
Another method is to use these :

Use Process Explorer to "Suspend" not Stop the Processes

Then use AutoRuns to remove the malware startup items.

Now use UnLocker to delete the files in the malware.

You may have to do this one file at a time.

Process Explorer - Free
http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx

AutoRuns - Free
http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx

UnLocker - Free (do not install the Ebay adaware)

AV.exe

==============================================

There are MANY varieties of these with many names however all can be removed with the
same methods :

Vista Antispyware 2010, XP Internet Security 2010, Antivirus Vista 2010, and Win 7 Antispyware 2010
are rogue antivirus, scams to force you to pay for them while they have no benefits at all.

How to remove ALL varities of this malware - please read the Removal Instructions carefully.
http://www.bleepingcomputer.com/virus-removal/remove-antivirus-vista-2010

RENAME these as needed to allow them to run : (use another name with the .COM extension instead of .exe)

These can be done in Safe Mode - repeatedly tap F8 as you boot however you should also run them
in regular Windows when you can.

Download malwarebytes and scan with it, run MRT, and add Prevx to be sure it is gone. (If Rootkits
run UnHackMe)

Download - SAVE - go to where you put it - Right Click on it - RUN AS ADMIN

Malwarebytes - free

Run the Microsoft Malicious Removal Tool
