I had received a notice during surfing that my mcbook is damaged by a Trojan horse, the technician said it's nothing to worry about. but I have bugs and I have no free storage! It doesn't make any sense,

why is the system data so big? and how do I solve this?

Lets see the output from the Terminal.app for the big picture before we get too carried away, copy&paste:

diskutil list internal

All that looks normal there , other than fact your user/home folder ( Volume ⁨Data⁩ ) is getting near full.

You can drill down on that data,

File size— list the items in the home folder with the sizes, including invisible items, copy & paste:

sudo du -h -d 1 ~/

SSD benefit having 15-20% free storage at all times....

addendum: Automator.app is in your Applications/Utilites folder a macOS built in app.
