Hi and welcome to the malwaretips.com forums!
I'm Jack and I am going to try to assist you with your problem. Please take note of the below:
Before we start:
Please be aware that removing malware is a potentially hazardous undertaking. I will take care not to knowingly suggest courses of action that might damage your computer. However it is impossible for me to foresee all interactions that may happen between the software on your computer and those we'll use to clear you of infection, and I cannot guarantee the safety of your system. It is possible that we might encounter situations where the only recourse is to re-format and re-install your operating system, or to necessitate you taking your computer to a repair shop.
Because of this, I advise you to backup any personal files and folders before you start.

Ok,please try to run this scan while your computer is in Normal Mode....

<li>Make certain that your PC is connected to the internet and then open the folder where you extracted Chameleon to and double-click on the Chameleon help file and then follow the onscreen instructions to use it.</li>
<li>If the Chameleon help file itself will not open, then double-click each file one by one until you find one that works, which will be indicated by a black DOS/command prompt window <em><>Note:</> Do not attempt to open <>mbam-killer</> as that is not a Chameleon executable and serves a different purpose)</em></li>
<li>Follow the onscreen instructions to press a key to continue and Chameleon will proceed to download and install Malwarebytes Anti-Malware for yo</li>
<li>Once it has done this, it will attempt to update Malwarebytes Anti-Malware, click <>OK</> when it says that the database was updated successful</li>

<li>Upon completion of the scan, if anything has been detected, click on <>Show Result</></li>

Before I go on, just wanted to verify something I read about ZeroAccess. Is it true that I once your comp. is infected with that it will never be secure again? It also says you must inmediately disconnect from internet to avoid identity theft. I want to know before I hook it up to my internet cable and start the process. Thanks for all your help.

The ZeroAccess rootkit is usually used to help the cyber criminals download further malware into the compromised machine. You can read more about this rootkit here: http://nakedsecurity.sophos.com/2012/06/06/zeroaccess-rootkit-usermode/
In your case the ZeroAccess rootkit looks like was used just to download that nasty rogue software so their is no backdoor trojan however I have to see the Combofix log before making any kind of conclusion.Just to be on the safe side, don't do any kind of transactions while using this computer and avoid typing in your passwords from different websites.

Have you tried to run Malwarebytes in Windows Safe Mode?
Most malware can not function in Windows Safe Mode including rootkits, therefore the scan should complete.
1. Reboot your computer
2. Keep pressing the "F8" key while booting until you come to the Safe Mode screen.
3. Select "Safe Mode with Networking"
4. After Windows completely loads, update Malwarebytes and try a complete scan.
Edit, looks like you already tried this, maybe Safe Mode is damaged try repairing it. http://blog.didierstevens.com/2007/02/19/restoring-safe-mode-with-a-reg-file/
Good Luck.

For some reason Kaspersky does not seem to install properly to my comp. The first time it looked like it did and after the scan was 1/2 way it shut down my comp. I started it up again tried it again but after several hours running it had only gone about 9% so I had to stop it from running to shut down and get to sleep. Now I am looking for the program to start it and it's not on the desktop, I did a search and found it in the downloads but it still looks like it's nost installed. I will try to install it again...
