Description of boost.exe from Reason Software Company
“Boost helps to restore the pep in your PC by removing crapware, bloatware, trialware, bundleware, and adware. Such “crapware” (and yes that’s an industry term) is known to cause system crashes, boot delays and just give your PC an overall sluggish feel. There are many forms of such extraneous software such as unneeded toolbars, adware, tracking programs, and other “free promotional software” to name a few. Think of crapware as being, just a whole mess of clutter that is causing your PC to feel bogged down.”
