Repack is a term used to describe programs that are copies of paid programs downloaded for free. Repacks can be both helpful and harmful to the user's computer, though it is usually advised for users to download the original paid programs only. Repacks can be fakes, resulting in demo of the program, game, or any other software. The Repacks are released by different Repack creating companies. The fake/danger chance of the repack released by a company is, as follows.
Fenix is one of these repacks. It is one of the most dangerous repacks, as it disables the cancel button when the HDD memory soft is installed, so the user can only kill this Repack only by restarting the computer.
Catalyst is another repack. This repack is slightly more safe, than Fenix. Like Fenix, it disables the cancel button, when the HDD memory soft is installed, but unlike the repack said before, it still writes setup log entries instead of "Please wait", finishing the setup, allowing the user to know, what this repack is currently doing.
THETA is a repack that is extremely rare. It is used to remove cost from very short group of programs. Like Catalyst, it will act like an ordinary setup program, but it doesn't disable cancel button before truly finishing the setup.
Sania.exe is a rare repack. It is used to remove cost from average group of programs and games. Like THETA, it doesn't disable cancel button before truly finishing the setup.
Archived repacks are commonly released by separate users, and rarely from Repack companies. They act just like an archive, and will require the user to setup them to the system manually.
