My PHP skills are really limited. Do you perhaps know what this error message is and how to get rid of it?

Not really, there's not much I can tell you other than find the code trying to call an exec() function.

This modifications requires no code changes. If you uninstall it and delete the files, the hack is gone, period. If you are still receiving errors, the problem lies elsewhere -- it cannot be this modification.

Apparently, it lies within a vBadvanced modification or vBadvanced itself. I'd start there.
