Is it malware that backspace gets unresponsive and acts on its own

Welcome to Major Geeks!

If you want to attach your logs we can check them out, but your problems sound like you are having hardware issues and the Hardware Forum or the Drivers Forum where you cross posted ( which you should never do ) would likley be a better place.

 

You need to attach all the logs requested in the READ & RUN ME FIRST cleaning procedure. We did not ask for a HijackThis log. The MBRcheck log is fine but that is from a thread for fixing Google Hijackers not the READ & RUN ME FIRST. The only log you attached from the READ & RUN ME FIRST is Malwarebytes. You need to attach the logs from the below scans:

• SUPERAntiSpyware
• ComboFix
• RootRepeal
• MGtools

Note that MBRcheck does show an Unknown MBR which may or may not mean your MBR is infected. Do you have your Windows 7 Boot DVD?

 

No. It will not help at all.


But perhaps you can do the below.


Create a Windows 7 System Repair Disc




Note: the below can only be done if your machine has a a type of CD/R or DVD/R optical drive installed. Also depending on the exact type of OEM your machine has you may be unable to actually create a SRD. The recdisc.exe program just may not even do anything. This linkhttp://windows.microsoft.com/en-us/windows7/Create-a-system-repair-disc maybe useful.

• Click on Start(Windows 7 Orb) >> Run...(or the Windows key and R together) to bring up the Run box, then copy/paste the following command into the box and click on OK:
  • recdisc.exe
• Allow the UAC(User Account Control) prompt via selecting Yes.
• You should now see a menu like the below:-

• Put a blank rewritable CD/DVD in your optical(CD/DVD) drive and then click on Create disc.
• Note: If a AutoPlay window pops up, just close it.
• When the SRD has been created you will see the below:-

• Now click on Close >> OK. Leave the disc in the drive as we will be using it shortly.
• You now have a Windows 7 System Repair Disc.

 

Did you try making that CD yet? You need to make it and then check to see if you can boot from it to get into the System Recovery Environment command prompt. Don't do anything while there. We just want to verify that you can get there now.

Also you need to back up important data before we attempt to repair your MBR. Normally there are no problems, but things can go wrong due to malware and thus the reason for backing up your data first.


Uninstall SpywareGuard as it outlived its usefulness many years ago and it will only serve to conflict with AVG.


Let's try to debug MGtools.



Please click Start, All Program, Accessories and you will see ( among other things ) a Command Prompt entry.

• Right click the Command Prompt entry and select Run As Administrator.
  • It is critical that you run it this way.
• If you do this properly, a command prompt window will open with a title of Administrator Command Prompt.
• Enter the below commands at the command prompt each followed by the enter key. The bold black are commands. The purple/brown is merely informational.

cd \MGtools <-- this changes to the MGtools folder and the prompt should change to C:\MGtools>
getnetinf <-- this will try to run all one scan from MGtools. Tell me what error messages, if any, you see.

nwktst <-- this will try to run all one scan from MGtools. Tell me what error messages, if any, you see.
GRK64 <-- this will try to run all one scan from MGtools. Tell me what error messages, if any, you see.
SN64 <-- this will try to run all one scan from MGtools. Tell me what error messages, if any, you see.

Now look for the C:\MGlogs.zip file and attach it no matter what happened while doing the above.

 

You did not uninstall SpywareGuard

After you get the CD made and have tested that you can boot from it, we can continue. The only potential issue you have is the MBR and I don't know for sure if it is actually the cause of your problems.

 

Yes, that is what MBRcheck showed as an unknown type.
