Trying to add an exclusion - excel vba program

[Steveacc]

Hi 

I have an application in excel VBA. It requires users (including myself when testing) to login to my webserver to validate id as a valid user.

Everything was ok until I upgraded to office 2016 on my PC but now Malwarebytes refused to run the program flagging it as an exploit.

I've tried adding the folder containing the excel file, the file itself and even excel.exe as exclusions but the damn thing still will not run unless I turn off exploits altogether.

How can I add my own vba application as an exclusion?

Is your Malwarebytes installed on the server.

No - just on my PC

I've tried adding my website address as an exclusion too.....still no luck. I've investigated further and its not the login that's the issue its the following

The offending code seems to be this:-

Code follows-----

myfile = "http://www.veloc.co.uk/velocfiles/secfiles/hello.txt"
result = URLDownloadToFile2(0, myfile, ThisWorkbook.Path & "\hello.txt", 0, 0)
'Check if the file downloaded successfully  and if it exists.
If result = 0 Then 'And Not Dir(FilePath, vbDirectory) = vbNullString Then
    'MsgBox "Success!"
    Set fshere = CreateObject("Scripting.FileSystemObject")
    Set a = fshere.openTextFile(ThisWorkbook.Path & "\hello.txt")
    teststring2 = a.readline
    a.Close
    Kill ThisWorkbook.Path & "\hello.txt"
Else
    GoTo nointernet
End If

and the report says

-Exploit Data-
Affected Application: Microsoft Office Excel
Protection Layer: Malicious Memory Protection
Protection Technique: Exploit code executing from Heap memory blocked
File Name: 
URL: http://www.veloc.co.uk/velocfiles/secfiles/hello.txt

hello.txt simply contains one line with a version number.....it reads this then closes and deletes the downloaded file. If the version number is not the same as in the local file then it prompts for the user to update.

First I suggest you upgrading to the current MB version so  we can rule that out.

 

[Steveacc]

Done

Any help? Please also restart the computer just in case.

[Steveacc]

Sorry....no. Doesn't help. (I've also restarted )

I managed to find a threat in the list and added it.....but it still blocks my program.

Its bizarre how it wasn't a threat in the old version of excel but is now.
