This probably doesn't help, but doesn't harm either. Let people who think it makes them safer use it, it might in some rare circumstances, who knows. But this doesn't make VAC more likely to detect a cheat, because the random code it adds to the end of a program isn't detected, so if VAC wants to scan it, nothing is going to happen. VAC scans all processes. You could release a 10kb cheat or a inflated 1GB cheat with loads of dummy code. If VAC gets their hands on it, they can detect both.
