Keep your computer and your confidential information free from viruses, spyware and malware by taking a few smart precautions.
- Ensure your computer is virus free
- Keep your home computer safe
- Protect your operating system

Anti-virus Scanning
Avoid infection from malware like viruses, worms, Trojans, and adware.
- Setup anti-virus software to automatically scan your computer in real-time or at least once a week.
- Enable real-time email scanning through your anti-virus program.
- Scan every file you download through the Internet or via email.
Securing your Home Network
Stay safe while you’re surfing at home.
- Use a personal firewall to protect your network at home. You can use a software or hardware-based firewall.
- If you use a router, be sure to change the default password.
- If you use a wireless router, encrypt your connection with a password.
- If you use a Cable or DSL connection, disable file sharing in Windows products.
Using Firewalls
A firewall is a program or device that inspects the information passing between your computer and its network connection. They block malware from gaining access to your computer. Firewalls also prevent the spread of malicious software from your computer to your network.
Personal Firewalls
Personal firewalls are programs that protect your computer from online intrusions over a network connection (e.g., wireless, Ethernet). When suspicious network activity is detected, the firewall blocks it and alerts you.
Windows:
Windows XP SP3 and all windows operating systems created after it (including Windows Vista and Windows 7) have a built-in firewall. For more information, visit: http://www.microsoft.com
There are several third-party firewall applications available as well, including:*
Zonealarm
Norton Internet Security
Lavasoft Personal Firewall
Mac OS X:
All Macintosh computers running Apple’s OS X operating system come with a built-in firewall. Please see http://www.apple.com for more information.
Hardware Firewalls
If you’re connected to a wireless or Ethernet router, your computer exists on a private network that has been created by your router. Therefore, your computer is not directly accessible to the outside world. Your router is your firewall and all access to your computer is granted through it.
Protecting your Operating System
Keep your operating system safe by updating it with security patches on a regular basis. Avoid losing any essential information if you encounter a problem, by backing-up your data regularly.
Permanently Deleting Files
When you delete a file on your computer, it is not gone forever. The information still exists on your hard drive until it is overwritten by new data. Identity thieves can retrieve personal information from your hard drive after you sell or donate your computer. A proper electronic file disposal procedure will make the information unrecoverable.
