Debugger now detected - process terminates. Thanks for the detailed instructions. Just tried it with "AstroAvenger2" from alawar - running .exe in Ollydbg triggers protection error message box - .exe detects debugger (WinIce.SoftIce) and terminates. Or have I bungled it? (newbie) Cheers!
I use Ollydbg with (IsDebuggerPresent) Plugin, check if for WinIce SoftIce are a plugin for that... not sure since never use those dbgs... Note: If you are actually using Ollydbg be sure to enable IsDebuggerPresent Plugin before loading the game or running it....
