False Positives - All VB6 programs


Recommended Posts

Hello.  Recently all my VB6 programs are getting quarantined after recompiling them.  The older ones that were compiled months or years ago are ok, but as soon as I make a change to one now and recompile it, it gets flagged as MachineLearning/Anomalous and quarantined as soon as I try to run it.  I'm attaching zipped exe's and reports for two of them, but it's really all of them it's happening to.   Any thoughts or ideas welcome.  Thanks.

Well here's three more.  Hopefully this helps.  I can't do them all.   After further testing I see that not all are treated the same by MWB:


Counter-blocked.zip:  The old exe from a couple of years go was blocked without recompiling it today.  The one attached here is after I recompiled it again today and it got blocked again.


morsflsh-ok.zip: The old exe from a couple of years ago ran fine and didn't get blocked.

morsflsh-blocked.zip:  After re-compiling it today it got blocked.


lights-ok.zip: The old exe from a couple of years ago ran fine and didn't get blocked.

lights-stillok.zip:  After recompiling it today this one was still ok and didn't get blocked.

Could you send me all of them please.

Thanks for trying to help.  Much appreciated.  They're all still getting detected and quarantined when I try to run them but it's ok.  I added exclusions for the folder they're all located in and I can use them again now.

Can confirm. 

I'm a hobbyist VB6 programmer and whenever I try to send a compiled executable to my friends, it gets quarantined on their end.

In fact, this is reproducible with a blank VB6 project. If you create a blank project and then immediately compile it without adding any code or content, the resulting EXE will be flagged as Anomalous 96% when unzipping or running.

I've compiled a blank VB6 app and attached it for demonstration.
