No two computer viruses are the same, but the worst ones can enable cyber criminals to steal your most personal information, destroy your data, and even damage your computer’s hardware.
Macs and PCs both have built-in firewalls that help shield your computer from malicious cyber attacks, but if you want an extra layer of protection, you can purchase and download a personal firewall.
