Compressed Game.exe

Hey forum,

I have a problem with my Game.exe. Other people keep telling me their anti-virus software blocks it because it apparantly contains a virus. After I changed my own anti-virus software, I also started finding trojans in it. I scanned the uncompressed game folder and everything's all right there, so the problem seems to lie in the way RPG Maker VX Ace compresses games itself.

Now, I have two questions. First, did this happen to you, too? And second, is there any point using the built-in compression over just zipping the game?

Kind regards

1) some virus software reacts because of its heuristic search - it doesn't find a virus, but a sequence of numbers that (in a different context) would create unauthorised access methods. That is because for a computer, everything is zeroes and ones, and the same sequence of numbers can be a program or part of a picture. And the key-sequences that the heuristic searches work on are shorter than the full virus, so they always generate a few false-positives.


There are a few pages on the internet that will check a critical file against a dozen virus scanners to see if it's a false positive or not - if only one or two of the scans report a virus, it's usually a fals-positive. If 80% of them report a virus, then the file really is infected.


(please note that even in the case of a real infection, not every scanner will report it - false-negatives are also happening)


2) the build-in compression is needed if you want to use encryption. OK, the game encryption is far from perfect - but you're legally required to use encryption if you're using purchased resources in the game to prevent everyone from just taking them from there.

Ah, I see! Thank you, Andar. I suppose "purchased resources" does also include Member+ stuff then, so I actually have to use the encryption, right?

RPG Maker is a common target for false positives. Many of the antivirus programs get their signatures from a common database, so you'll find when one reports it, a lot of others using different software will start reporting it as well. It's not your game, it's the antivirus program
