I checked it with mcafee and several antispywire programs, and it doesn't contain any malicious software, it does OPENLY send information about what game you're playing and keeps track of how many hours you play such game, that's one of it's purposes, so it's not spyware, it's a feature.
Also, automatic download in the background can be disabled.
No one forces anyone to use it, but it supporting Aces High 2 would only be an advantage for the ones that do.
