Ok, I will verify the checksum, but How ?
On a Linux machine - open a terminal (konsole) and change to the directory

then type in:
md5sum Toorox_06.2009.iso
it takes a few seconds then it will show you the result.
Compare this with the md5sum in the Download section.
Most burning applications have an option for calculating the md5sum of a file, too.
