@Kas Ob. @Clément Thanks for this discussion. 🙂 Adding {$DYNAMICBASE ON} appears to please CrowdStrike also. Delphi 10.4.2, New Windows VCL application (that's it...just an empty form), 32-bit, Release config https://www.hybrid-analysis.com/sample/e8a4cdfe94031025baafff9924d82210bd74b4088607fa369b30deeb83e72480 Same as above but with {$DYNAMICBASE ON} https://www.hybrid-analysis.com/sample/86e9c1fe77dbe5cfc962dce19e79e7a7930b92dd1ba90cba60395d5998995c1b

@Kas Ob. Great news!!! I try all your suggestions, either alone and combine in the 32 bit release only. Here are the results. 1) Including DEP directive. ( Did NOT trigger Windows defender ) I included {$DYNAMICBASE ON} in my DPR as follows: {$R *.res} {$R 'D:\Projetos2k10\Projects V\DHS\SQL explorer II\src\resource\cKwel_versioninfo.RES'} {$DYNAMICBASE ON} // Enable DEP, works also when using {$SetPEOptFlags $40} begin // try {$IFDEF DEBUG}ReportMemoryLeaksOnShutdown:= true;{$ENDIF} Application.Initialize; Application.MainFormOnTaskbar := True; Application.Title := 'cKwel - Query Tool'; Application.CreateForm(TdmSkinController, dmSkinController); Application.CreateForm(TdmImages, dmImages); Application.CreateForm(TdmLookAndFeel, dmLookAndFeel); Application.CreateForm(TdmEditRepository, dmEditRepository); Application.CreateForm(TfrmMain, frmMain); Application.Run; // except // end; end. 2) Changing /modifying icon TRIGGERS Windows defender 3) Encapsulate all the content of the main in dpr with try..except did NOT trigger Windows defender: {$R *.res} {$R 'D:\Projetos2k10\Projects V\DHS\SQL explorer II\src\resource\cKwel_versioninfo.RES'} {.DYNAMICBASE ON} begin // Enable SEH by setting all code between try..except. try {$IFDEF DEBUG}ReportMemoryLeaksOnShutdown:= true;{$ENDIF} Application.Initialize; Application.MainFormOnTaskbar := True; Application.Title := 'cKwel - Query Tool'; Application.CreateForm(TdmSkinController, dmSkinController); Application.CreateForm(TdmImages, dmImages); Application.CreateForm(TdmLookAndFeel, dmLookAndFeel); Application.CreateForm(TdmEditRepository, dmEditRepository); Application.CreateForm(TfrmMain, frmMain); Application.Run; except // No code is required here end; end. 4) Fill the EXE description, version name copyright TRIGGERS windows defender. I don't know if the combination should produce some valid results, but any combination that includes 1 or 3 works. For example 2 and 4 will TRIGGER windows defender while 1, 2 and 4 WON'T trigger it. Cool! Hope this thread will help others!

I'm using DHTML extensively for SVG: https://delphihtmlcomponents.com/ I tried a couple others but DHTML gives better re-sizing (really smooth without flickering) and was better at handling the SVGs I work with (generated by matplotlib).

Thanks for all hints. I created a subclass of TMenuItem and did an override of the AdvancedDrawItem method. In addition I set Enabled=False. Themes are not support, but I don't have that anyway in my application. But so far it looks fine: procedure TMenuGroupItem.AdvancedDrawItem(ACanvas: TCanvas; ARect: TRect; State: TOwnerDrawState; TopLevel: Boolean); begin ACanvas.Brush.Color := TColors.Silver.Lighten(50); ACanvas.FillRect(ARect); ACanvas.Font.Color := TColors.SysWindowText; ACanvas.TextRect(ARect, ARect.Left + 3, ARect.Top + 3, StripHotkey(Caption)); end; Christian

I wouldn't wish the bank 1 to know about my state in bank 2.
