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.

Thanks for noticing and getting this posted so fast.

Thanks for heads up. I've been spreading the word.

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.

Nice catch!

[drmsucks]

If a system is experiencing no problem, should the fix be run?

What are the symptoms of the bad SecurityProviders values?

[evilfantasy]

No symptoms that I am aware of, the bug was actually discovered by someone not affiliated with MBAM.

Yes it needs to be run, if the Security Providers values are faulty, it will tell you and then fix it.

Can i still run it correctly if I have removed MBAM after using it?  I ran it on my laptop (even tho MBAM is not longer installed), and it found no errors...

[evilfantasy]

It will work the same with or without MBAM installed.

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.
