Is their a program that will scan my HD and go to the internet and search for my programs update to download?

Answer 1

Let me see if I can help explain.
Many Software programs will give you the option when you download them, to search for automatic updates. By choosing this option, Your computer will automaticly upate that program.
Then there are others that do not have this option to choose.
When that is the case, It is a pain I know but this will require you to occasionally check the Manufactures web site for any updates for there software. I normally do this every month or so.
