Pat, aha a common problem.
You have Windows 7, internet explorer 7 would not have been preloaded on your computer, if anything it has IE9 preloaded if it's pretty recent.
Here is how you get rid of it,
Click on the little windows button the lower left hand corner.
Go to computer
Along the top you will see "Organize/ System Properties/ Uninstall or change a program
Click on uninstall or change a program
This will make a list of all programs on your computer
Now on the left hand side of that window you will see "View Installed Updates"
Click on that
There will be a lot, Adobe, Microsoft Office, Windows etc.
Scroll down through the list until you see the one that says Internet Explorer 9 or IE9 I cannot remember since mine is uninstalled
Highlight it and up on the top you will see "Organize and Uninstall"
Click on Uninstall, you will get a warning about removing it, do it anyway, click continue.
You may have to reboot I cannot remember, but this will roll it back to Internet Explorer 8.
See much more complicated lol.
But you should be able to do it now.
