Took a look at the files installed for FoneLab... There is a file: Adagent.apk -- an apk file is an Android setup file -- running it will install an Android app -- using Google, "adagent.apk" [with quotes] yielded zero results, so no idea what this is or does. On the download page Karl posted that the security software on his Android cell warned of Framaroot, which is an Android app to provide one-click rooting of an Android device. In the root subfolder [in the program's folder: FoneLab for Android] there are 9 files, 2 of them are framaroot1.bin & framaroot2.bin, with a third being Superuser.apk. That latter does come up on Google -

Note that the Superuser app requires root access.
I don't feel that this is the time/place for a in depth discussion of rooting your Android device, but know that there may be legal issues, as well as issues with your cellular carrier & warranty should you decide to root your device.
It's not entirely unreasonable for certain types of software to require root access so that they can get full access to the files on your Android device. But You Should Be Forewarned as You Bear Any Consequences.
At the moment the last post on the download page says more-or-less, well give us an alternative. The surest alternative is to back up your device, same as you should all your devices.
