I'm not the greatest when it comes to computer code-type deals, but my internet randomly started going slow/off and I found this:

(There was much more, that's just a portion)

I'm not sure how to go about fixing this as I'm relatively bad with firewall rules/etc. I read about wireshark, got it, and have no idea how to use it. I've gotten help on here a couple years back to build a pc, so i figured it was worth a try to ask for help again.

There is little you can do your router is already protecting your PC because nothing is getting past the router. And because it know this is a attack it does not respond in a way that is helpful to the attacker.

You can't really prevent the packet from using up your bandwidth because your router has to see it before it can do anything and since it already knows this is invalid traffic it will drop it. You would only be at risk if you had configured your PC to be in a DMZ or mapped a lot of ports though to your PC.
