Set up Windows Firewall

When it comes to securing your PC, be sure to enable a firewall. A firewall is used to prevent unwanted connections being made to your PC. Malware, such a worms, can scan a machine to see if certain ports are open and if so will attempt to access your machine via those open ports.


Windows comes pre-installed with a basic firewall and while you can’t configure it too much, it’s certainly worthwhile making sure that it’s enabled.


Ad-Aware Pro includes a powerful two-way firewall, but if you’re using Ad-Aware Free it’s a good idea to make sure that Windows Firewall is enabled even if you’re behind a router.


Once your firewall has been enabled, you can test your systems firewall defenses with ShieldsUp!!, a free scanning tool available at www.grc.com to check that it is secure.
