False Positive MachineLearning/Anomalous.100%: VB6 program


Recommended Posts

Sorry to be that guy still using Visual Basic 6. This executable is being flagged for MachineLearning/Anomalous.100%. What is strange is that I have several apps created in VB6 that do not get flagged. Some required some tweaking but I hit a wall with this one. Also, it uses 99% of code used in programs that did not get flagged. I even removed the 1% of code that was new and the false positive remains. Let me know if you would like the other programs.

Hello @BillReilly

Can you please post back the actual log file showing the detection as well as zip up the file and attach so that we can review.


You can find Scan and Protection logs within the Malwarebytes 4 program in the following location




RTP stands for Real-Time Protection and is where automatic protection operations would normally be logged




If you click on the View option you should get something similar to the following with other options available.





Thank you

These files are harmless, they just happen to have the name vb6.* so they are getting flagged for no reason... I thought this problem was fixed a month or so ago but obviously that fix got rolled back or somebody made a mistake.

I've had other problems with Malwarebytes so if you don't fix this I'll have no choice but to uninstall it from all of my PCs.

Do you have "Use expert system algorithms to identify malicious files" enabled? It is located in Settings > Security> Scan option.


This is normally disabled by default.

This was detected by our machine learning engine and we advise developers to whitelist the folders they develop in. For more information on why it might have been detected, please read MachineLearning/Anomalous Detections and Explanation.

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