I'm Infected, Can't install Malwarebytes or others

[BNBarnes8]

So, for the past few days I've had strong suspicions that I might be infected. I done a full scan with current anti-virus but it didn't really detect anything. So I tried to download Malwarebytes and other anti-virus'. They all download but when I try to run their installers a box pops up to tell me it's not a valid win 32 program. And I'm getting frustrated, especially since my knowledge of computers is pretty low. Could someone help me?

Hello BNBarnes8 and welcome to Malwarebytes forum.

 

The chances are almost certain that the pc is infected with a very serious malware rogue that is blocking the running of most all security softwares.

That is why the Anti-Malware is not able to install.  It takes special procedures to hunt for and remove these types of malwares.

 

Please download Malwarebytes Anti-Rootkit (MBAR)  and save it to your desktop,
from here   
http://downloads.malwarebytes.org/file/mbar

•Be sure to print out ( if possible) and follow the instructions provided on that same page.

•Doubleclick on the MBAR file you downloaded and approve the UAC prompt in Vista and newer operating systems.
•Click **OK** on the next screen, to allow the package to extract the contents of the file to its own folder, mbar.
•mbar.exe will launch automatically. On some systems, this may take a few extra seconds. Please be patient and wait for the program to open.
•After reading the Introduction, click '**Next**' if you agree.
•On the Update Database screen, click on the '**Update**' button.
•Once you see 'Success: Database was successfully updated' click on 'Next'.
•Click the '**Scan**' button.

With some infections, you may see two messages boxes.
  1.'Could not load protection driver'. Click 'OK'.
  2.'Could not load DDA driver'. Click 'Yes' to this message, to allow the driver to load after a restart. Allow the computer to restart. Continue with the rest of these instructions.

•If malware is found, do **NOT** press the Cleanup button when the scan completes. Click EXIT.
Then, please send the following logs as attachments to your reply. These logs are located in the mbar folder on your desktop where the tool extracted itself to.

**mbar-log-2014-06-xx(xx-xx-xx).txt** (where xx-xx(xx-xx-xx) is the date and time of the scan)
+ also
**system-log.txt**

I need to have both of those files attached in your next reply.  Thanks.  **Send even if nothing is reported as detected. Always send these.**

Double clicked on that file and its telling me that the application has failed to start because it's side-by-side configuration is incorrect.
