Try disabling Norton and installing if you're sure it's not being blocked because a virus is being detected

I have been having trouble for some time installing programs, these programs are not of one type they can any type for instance I have just been trying to install Draftsight
from Dassault Systems I downloaded it from their, site saved it, and proceeded to install it but it gets to the section where the program is gathering info then freezes, so the next thing I did was to reboot in safe mode as I had saved it therefore didn't need a Wi-Fi connection proceeded to try and install it again this time I got a bit further then it stopped with an error when it was loading files, I have had the same problems with other programs since reinstalling W8.1, it seems as though something is blocking the installations I thought it might be the firewall (this is managed by Norton) what do you folk think?
