Yes, your PC can run it

If your PC can run the full version of Windows 7, it can run Internet Security. Period.

You need at least Windows XP (with SP2) installed. Windows Vista, 7, 8, and even 8.1 are fully supported (unless your device runs the Starter or RT edition) in both the 32- and 64-bit variant. A 10-year old Pentium 3 processor will do, with 128 MB RAM and 1 GB of hard-drive space. And now imagine the stellar performance with your new hardware!
