jZip was mentioned a few times on SU, the problem is that it is possible malicious software.

The most prominent problems I've found are:

• The website was registered via a proxy service, there's no way to figure out who owns it
• The website seems to be associated with the Panthera Project, which is a project of the Discordia Limited company, part of the RIAA 'P2P hunters'.
• A scan on virustotal.com of the Setup didn't reveal anything, but I'm not eager to test it out by installing it

Yes, I know that this is very vague information...so, shall I further investigate this or leave it be?
