I originally posted under the general forum but they sent me here. I was infected with a virus but I am clean now. MSE has run and cleaned my computer, I have also run many scans and posted logs at a similar site and they have said that I have no malicious files on my computer and sent me to this forum for help. The only remaining problem I have with my computer is that I cannot load Malwarebytes. The following is my original post:

I am running windows 7 on a desktop computer. I did have a virus and ran an old Malwarebytes with an old data that I had and it seemed to remove most of the virus. When I went to update data file I was told there was a new version of Malwarebytes, it unloaded the old version and went to load the new version. I get through all the propts and almost to the end of the install process where it says "Access Denied", then "setup was not completed. Please correct the problem and run Setup again" it then rolls back the changes and doesnt install. Any help would be appreciated.

Hello sjbells.

Please advise if you have resolved your issue. If not, and you need guided help, please do the following.

Step 1
1. Go >> Here << and download ERUNT
(ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.)
2. Install ERUNT by following the prompts
(use the default install settings but say no to the portion that asks you to add ERUNT to the start-up folder, if you like you can enable this option later)
3. Start ERUNT
(either by double clicking on the desktop icon or choosing to start the program at the end of the setup)
4. Choose a location for the backup
(the default location is C:\WINDOWS\ERDNT which is acceptable).
5. Make sure that at least the first two check boxes are ticked
6. Press OK
7. Press YES to create the folder.

Step 2
To show all files:
  • Go to your Desktop
  • Double-Click the Computer icon.
  • From the menu options, Select Tools, then Folder Options.
  • Next click the View tab.
  • Locate and uncheck Hide file extensions for known file types.
  • Locate and uncheck Hide protected operating system files (Recommended).
  • Locate and click Show hidden files and folders and drives.
  • Click Apply > OK.
Step 3
Download Random's System Information Tool (RSIT) by random/random from here and save it to your desktop.
  • Double click on RSIT.exe to run RSIT.
  • Click Continue at the disclaimer screen.
  • Once it has finished, two logs will open. Please post the contents of both log.txt (<<will be maximized) and info.txt (<<will be minimized)

Step 4
Download Security Check by screen317 and save it to your Desktop: here or here
  • Run Security Check
  • Follow the onscreen instructions inside of the command window.
  • A Notepad document should open automatically called checkup.txt; close Notepad. We will need this log, too, so remember where you've saved it!

Step 5
Close all open browsers at this point.

Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools
For directions on how, see How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs
Do NOT turn off the firewall

Start Internet Explorer
Using Internet Explorer browser only, go to BitDefender Quickscan website:
http://quickscan.bitdefender.com

and click "Start Scan".
Observe your browser in case it shows a notice/message bar to allow download and installation of a tool.
Allow the download and install of qsax.cab from BitDefender. Right-click the IE info bar and select Install to install the BitDefender quick scan module.
If prompted, reply yes to allow it to run.
Press the Allow button and follow prompts.

Press the "Start Scan" once more.
You'll see the EULA in a pop-up window. Click the I accept & then the OK button

Note: The FAQ is here --> http://quickscan.bitdefender.com/faq/
and that QuickScan has no removal capability.

The site boasts a 60-second scan. Do have patience as it likely will take longer.
It may seem to stall at moments, but have patience; it will move on.
You'll see a progress bar at top right of window.

Hopefully you will see a No infections found in the bar-winddow. Press the View Log button.
The log report will show in your text editor. Save the log.
Do a Select ALL, Copy. Then paste contents into your next reply.

RE-Enable your antivirus program.

Copy & Paste contents of Log.txt & Info.txt & Checkup.txt & log from Bitdefender.
Use separate replies as needed if logs do not fit into one reply box.
