Make sure to use strong passwords for all of your accounts and programs. Consider using a password manager so you can create and remember strong, unique passwords for each account. 2 Use a reliable antivirus program and keep it up to date. Additionally, keep your other software and security patches up to date, install a firewall, and use a VPN when possible. 3 Consider enabling two-factor authentication for extra security. This adds a second layer of protection, requiring a unique code in addition to your password for access to an account. 4 Frequently review your system logs（or network logs）and look for strange activity. If you detect any anomalous activity, take immediate action to stop or mitigate it. 5 Regularly back up your documents and data so if your system is compromised, you don't lose your important information.
