Sumoto pays money to programmers to include "sidecar" programs from advertisers and marketers.
When you install a program that secretly uses Sumoto, you may accidentally also install many tracking and control programs.
Use "manual" options to DECLINE added programs, and then run malware removal software after, such as Spybot Search & Destroy and others to remove the unintended "sidecar" invasions.
Sample executables installed from "temp" directory:

Their toolbar causes drivebys of various kinds - they are also responsible for "betterinstall.exe" which will forcefully install any number of addons, etc. Even when you reinstall this app, it will re-install additional toolbars or addons - nasty piece of work.
