- Be sure to turn on auto-updates for Operating System and apps.
- Host Operating System as well as other Host Operating System.
- Applications (mobile and also on computer, drivers, etc.)
2. Ecrypt Data.
- Modern Phones, Macs and most Linux have it by default, check that it is on anyway.
- For windows users u can use other tools like Veracrypt (Make sure that you have a backup first).
3. Have an antivirus and anti-malware (but don't install two or more, since they might not work properly that way).
4. Passwords.
- Have safe passwords, no "password", no "12345678", no "77777777", etc.
- Don't use the same passwords for different things.
- Consider using a password manager, it can be your computer's keychain or a third party manager you trust.
