A "planet" traveling at the speed of light would need to be composed entirely of photons, and (assuming an Earth-sized relativistic mass) would have 5.37x10^41 J of energy. That's around 2.3x the gravitational binding energy of the Sun, so I assume it would be obliterated, along with all of its planets.
Fun fact, the kinetic energy a comet would gain from falling into the Earth's gravity well is around 60MJ/kg, more than two orders of magnitude greater than the energy which would be absorbed by it melting (0.33MJ/kg).
The cargo holds on commercial flights are pressurized and heated. I can't imagine passengers would take kindly to their luggage being subjected to 0.3x atmospheric pressure at -55°C.
Didn't realize Edge actually had a file named setup.exe used for uninstalling. Though it's quite suspicious they'd include their own file instead of using the one already included with Edge.
From a quick glance, there's a "setup.exe" file in the source directory, which seems very sketchy. Sources should generally contain source code, not precompiled executables. I certainly wouldn't chance it.
Edit: According to VirusTotal, it attempts to connect to sb.scorecardresearch.com, a tracking service. It also apparently creates a scheduled task. Definitely do not use this software.
Whatever you do, make sure you have a backup! There's always the possibility of screwing something up, no matter how careful you are (or your hard drive deciding to spontaneously self destruct).
Some intern is having a bad day right now.
