The Web Browser
- If pages don't refresh as expected, you may have to clear the browser's cache.
  - How to clear the browser cache in Chrome. The procedure in other browsers may differ.
Antivirus
- On Windows you should run two independent antivirus system.
  - The included Windows Defender (Or whatever it's currently called).
  - A second service like AVG, Malwarebytes, Avast, etc. I do not recommend McAfee as it's more malware than useful. If the System Admin has to work on a computer with McAfee, it gets deleted as the first step. You can reinstall it yourself later.
  - This doesn't mean run five. You can get things too locked down and never figure out what system is restricting what you are trying to accomplish.
Firewalls
- Set your firewall to block unnecessary incoming connections. This is usually ALL connections on a non server device.
  - Block inbound connections on Ubuntu.
  - Blocking inbound connections on Windows 10.
