For the future just post the log instead of zipping it up.

It would help if you zip the actual file and attach it as well. C:\PROGRAM FILES (X86)\REAL\REALPLAYER\CODECS\DMP4.DLL

Hi,

This is indeed a false positive by our additional machinelearning engine we have implemented.
This will get fixed.

Thanks for reporting!

Hi I also received a warning about the attached file for Malware.Heuristic.1001 but believe it is a false positive.

Below is the log and I have also attached file. Thanks.

Please turn off "Use expert system algorithms to identify malicious files” It is located in Settings > Security> Scan option to avoid these detection's

It is off by default.

FYI. This setting is in the experimental stage.

That setting is to detect malformed files, but sometimes legit files use protection that make them malformed. Malwarebytes is still tweaking the algorithms that is why it’s off by default. If you switch it on it is assumed, you can tell the difference between a FP and a legit detection. 

And if you keep it on, I suggest also turn off auto quarantine. Gives you the time to report FP's and not go thru the extra step to have to restore from quarantine.

Thanks for reporting, this will be fixed in 10 minutes.
