Method 3: Safe mode: Rename the malicious driver by using the command prompt

Start your computer in Safe mode.
Start >> Run >> cmd
At the command prompt, type CD %windir%\system32\drivers, and then press ENTER.       
Type "dir /a" press ENTER.   
You will see text that is similar to the following text (the .sys file name will be randomly generated):

Directory of C:\WINDOWS\system32\drivers

01/11/2005  09:18 AM               13,824 gbqxmhia.sys
               1 File(s)            13,824 bytes
               0 Dir(s)     961,425,408 bytes free

       
Type Attrib –s –h <randomfilename.sys>, where <randomfilename.sys> is the name of the .sys file displayed earlier, and then press ENTER. For example, the command for the file name earlier would be as follows: Attrib –s –h gbqxmhia.sys This removes the system and hidden attributes from the file.       
7.       Type Ren <randomfilename.sys> malware.old , where <randomfilename.sys> is file name as mentioned earlier, and then press ENTER. This renames the randomly named file. 
8.       Type "CD ..", and then press ENTER. This changes the command line to the \Windows\System32 directory.      
9.       Type the following commands one at a time, and press ENTER after each line:
Ren msupd5.exe msupd5.old
Ren msupd4.exe msupd4.old
Ren msupd.exe msupd.old
Ren Reloadmedude.exe Reloadmedude.old
Note If you receive the following error message, you can ignore the message because it indicates that the file does not exist:
The system cannot find the file specified.
Type Exit, and then press ENTER.      
Restart the computer. 
Make sure that your antivirus/antispyware software is updated with the latest signatures, and then perform a complete system scan.
