Безопасен ли modarchive.org?

Nothing more but an archive containing "tracker modules". A "Tracker" is a program in which you can write music in the "Tracker" script. During the AMIGA years this was THE way of writing music (with programs like SoundTracker and ProTracker) and when Commodore went bankrupt newer programs like FastTracker2 and Scream Tracker took it over in MS-DOS scene. The Tracker scene is not a huge as it used to be, so the stuff you can find here is pretty old, but a lot of them still great and that's why this archive was set up, in order to preserve the good old days. The worst thing I ever downloaded here was a poorly set up module (as this site contains stuff from artists of all levels. Good ones and bad ones). But that doesn't come nearly close to malware, now does it. It has a Java applet that allows you to play modules online and as far as I know it's safe.
