MalwareBytes Critical bug, please read

It has come to our attention that a critical bug existed between Malwarebytes' Anti-Malware version 1.00 and version 1.25. If you ever removed anything using Malwarebytes' Anti-Malware during that time, please run the attached file. Your SecurityProviders value may have been corrupted.

The original values of the value should have looked like this.
file1.dll, file2.dll, file3.dll

When repairing the registry value, Malwarebytes' Anti-Malware may have reset the values to the following.
file1.dll file2.dll file3.dll (note lack of commas)

This has already been repaired in version 1.26, however, those exposed to this bug must be repaired. Attached is a utility that will tell you whether the registry value is corrupt and it will offer to fix it by adding the necessary commas. We apologize for the problems this may have caused and we hope to never have a repeat of this situation.

Simply download the file to your desktop, unzip it, and run it.

Version 1.27 will repair these registry values so even if you don't run the fix as long as MBAM is updated it will be repaired.

More information.

This particular bug would only affect you if your computer was part of a LAN in a configuration that required it authenticate itself to others. It has nothing to do with antivirus, or security otherwise.

MBAM v1.27 is now available.

As long as everyone who has at one point used MBAM to fix anything updates their copy of MBAM the bug will automatically be fixed.
