First things first, there are no "quick fixes" other than restoring your system from a backup taken prior to the intrusion, and this has at least two problems.

1. It's difficult to pinpoint when the intrusion happened.

2. It doesn't help you close the "hole" that allowed them to break in last time, nor deal with the consequences of any "data theft" that may also have taken place.

This question keeps being asked repeatedly by the victims of hackers breaking into their web server. The answers very rarely change, but people keep asking the question. I'm not sure why. Perhaps people just don't like the answers they've seen when searching for help, or they can't find someone they trust to give them advice.

A Glue Record is the IP Address of a name server at a domain name registry. Glue Records are core parts of DNS records because they help to resolve DNS servers at a core level.

Without this, a domain name will not work because anyone requiring the DNS information will be stuck in a loop. There is a cyclic dependency of circular referencing. Circular references exist when the name servers for a domain can't be resolved without resolving the domain they're responsible for. So, a Glue Record is an additional A record that allow the DNS client to locate name servers.

Eventually, I did start to wonder if running a firewall might be worth the hassle of its upkeep; after all many networks run them by default, and your friends and family probably have a firewall running without them even knowing. In trying to decide whether I should do a firewall myself, I got a pros and cons list going and I thought I'd share it here. So here we go.
