I am using this gboxapp toolbar in my PC since I know the toolbar, it may be 4-5 months without any problem. I am enjoying its most of the features. but recently one of my facebook friends told me it is not useful. it contains malware. I knew about it just search.gboxapp in google. Now I need to know it is really Helpful/ harmful. Help me please.

Why the hell you need a useless toolbar at the first place ?
I find toolbars annoying , intruding and wastage of space.
Uninstall it at once.
