My computer runs Window 7 and Internet Explorer and my Internet provider is Comcast. Comcast has a system called Constant Guard that notifys me of a problem with my system. The other day CG flashed a message that Google Chrome was taking up space on my Hard Drive. I have never downloaded Chrome so I searched my programs and it is not there. How do I determine if Chrome is on my computer and taking up hard drive space? Thanks for your reply.
