Get the latest version of iTunes - Apple Support explains the process of ensuring that you have the latest version of iTunes.

The image you posted "looks" legitimate. When I use ⌘+I on the .pkg I get Size: 239,751,638 bytes (239.8 MB on disk), what do you see?

What makes you think that your computer is "hacked?"

To add on to what AppleTechTips said : if your machine shows signs of having adware/malware installed (like getting ad pop-ups on websites which don't generate ad pop-ups, like apple.com for example), you can download this and run it, it's free : https://www.malwarebytes.com/antimalware/mac/
