As a number of others have noted this error has shown up in ver (current). Error says "cannot find file specified". So -- to eliminate yet another hour wasted reloading MBAM, etc. exactly which file cannot be found and where is it located? I will back up same so in future will only need to restore "specified" file.

thanx, Sam Dawson

Hello Sam16 and welcome to the Malwarebytes Forums.

We have a batch file that will do exactly as you have asked. It will delete the rules.ref file and then force an update to replace the file. Please download the attached file to your desktop and then unzip it to run. Make sure to run the file as Administrator by right clicking the file and selecting "Run as Administrator" if using Vista or Windows 7.

This should take care of the issue.

Please try the following:

  • Download and run mbam-clean.exe from here
  • It will ask to restart your computer, please allow it to do so very important
  • After the computer restarts, temporarily disable your Anti-Virus and install the latest version of Malwarebytes' Anti-Malware from here
    • Note: You will need to reactivate the program using the license you were sent via email if using the Pro version
    • Launch the program and set the Protection and Registration. Then go to the UPDATE tab if not done during installation and check for updates.
      Restart the computer again and verify that MBAM is in the task tray if using the Pro version. Now setup any file exclusions as may be required in your Anti-Virus/Internet-Security/Firewall applications and restart your Anti-Virus/Internet-Security applications. You may use the guides posted in the FAQ's here or ask and we'll explain how to do it.

It should be very simple if you're having such issues its possible you may have some infection causing it.

I would recommend you have someone review your system to ensure it's not a malware problem first.

Here are the steps needed to get your computer cleaned....

Please read the following so that you can begin the cleaning process:

Don't use any temporary file cleaners unless requested - this can cause data loss and make recovery difficult

PC # 1 MBAM working fine and PC # 2 MBAM installed but shows error; will not open.

I copied rules.ref from PC#1 and was able to open and scan PC#2. MBAM showed no infections on PC#2. I ran update for MBAM on PC#2 showed 7+ meg file downloading and then same error code. But again I could replace rules.ref file from PC # 1 and MBAM would open and run scan.

Ideas on the rules.ref file?

Only that it would appear some process or setting is blocking, preventing the rules update from completing on PC#2

Could be your Anti-Virus, could be other security software, could be an infections, could be a hardware issue.

Why don't you check out what you can like maybe temporarily disabling your AV and see if updates work and if you can't find anything then follow the other advice and have someone assist you in checking it for an infection.
