It's compressed, as 450 said. I will look out for another version but I won't use one that's as large as 122KB. The bigger the SFX file, the bigger the outputted installers. But this is really a lost battle. If I find one which isn't flagged as a trojan, it may so in a few months. A lot of anti-virus software manufacturers are just lazy and flag all files compressed with a certain method as a trojan if one virus maker happened to use the same compression method for his virus, instead of checking what's inside of it.
