Yo.

OG. Source from Scripter4Ever, however I've updated it to VB.Net standards and cleaned it up.

This, is what either of LoadLibrary entry points look like before execution of the code:

This is what it looks like after:

The first statement of LoadLibrary was just replaced by a return statement, causing any dll injector using LoadLibrary to fail (because when LoadLibrary is being called, it just returns without loading the actual dll into the process).

Hope you guys enjoy, I wouldn't rely on this too much though as it'd be fairly easy to reverse, but none the less it gets the concept across.
