Important info about 'Winject'

Okay guys you've all probably heard of/used winject in the past right?
Well I downloaded the official link from this site here and used it to inject a dll hack into crysis, well after about two days my norton protection flagged winject from trying to connect to an outside source?
so what i'm starting to think is winject is a part of a dos shell or something
be careful when using WinJect ok
