How do I delete upgraded version of Safari and then reload older version?

Upgraded Safari when prompted.   Safari7.1  uploaded, then woudn't open, says it requires OS 10.9.1 to work and wants me to upgrade to Yosemite from Lion. I want to  delete the new upgraded Safari because it doesnt work with my older OS,  and reload the older version of Safari (6.5.1).  but i get message saying "can't delete the application because the OS needs it to function."  So what do I do next? Does this mean there is a malware that was downloaded in the upgraded version of Safari? When I click on the Safari version Get info, says it is 7.0.4, installed in 2011. Icon has a line bar through it and is faded, in menu bar and on logo version in Apps folder.
I am running MacBook Pro 2011,  OS 10.7.5 Lion;  2.4 GHx Itel Core i5, 4GB 1333MHz DDR3.

That's actually kind of odd as Apple usually will not allow an incompatible install of software, especially from their own server.

The easiest way to get it back is to recover from Time machine, if you're running that. Just select Safari on a date earlier than when you did the update and you should be good.

I've seen some third party apps that say hey will replace Safari, or any application, but I've not used them and can't recommend them.  One of the easiest ways is to reload the OS. When you boot your Mac, do it with CMD-R held down and it will boot to the recovery partition. Reloading OS X will only replace the OS X system.  It won't mess with your applications or data. It will replace Apple applications like Safari with the original version. Of course the usual caveats apply about making sure yo have a good backup of your data. Before starting down the reinstall process itself, you can, from the recovery partition, do a check of your disk and your permissions. It's always advisable to do this before making any sweeping changes like restoring the OS.  When the recovery process is done, OS X will be back to the state it was in when you bought the system. You will need to reload any patches or updates that you installed.
That's one of the reasons why I don't use Safari except for special cases.

You can also move it out of the way from the command line.

sudo mv /Applications/ ~/.Trash/

It should prompt you for your password.

I did try to reload Safari from Time Capsule, from before the upload, but when I try to open it, it still acts like it is the updated version, and gives same message that it requires an updated OS to work.
