Protecting your hardware:

• Set up an auto update in Windows or go to http://windowsupdate.microsoft.com at least once a week and install all critical patches
• Run an antivirus program at least once a week. Update your virus signature files every time you use it.
• Use a firewall such as Zone Alarm.
• Check your computer for trojans by clicking on: http://security.symantec.com http://www.windowsecurity.com/trojanscan/
• Don’t click on e-mail attachments without screening them first.
• Don’t install Napster, Kazaa, ChainCast, or any software from an unknown source. The former will turn your computer into a server and the latter may contain trojans and viruses.
• Turn off sharing (in a network environment such as your office), especially on your C:\ and D:\ drive. This is dangerous. If you must share a disk, make sure it requires a password. Otherwise, anyone in the Internet can use your computer to back up their files without your knowledge. Never share any folder without a password.
• Put a good password on your PC. If you have a password on your PC that is easy to guess, your computer can be easily taken over by hackers.

Safe Web browsing:

• Whatever Web browser you choose, be certain to download all updates and familiarize yourself with the built-in safe surfing features, and tweak the settings to ensure a high degree of protection. Most Web browsers are now able to warn you if you are about to go to a fraudulent site (especially a phishing site) or if a download poses a possible risk — but note that no Web browser is able to identity every fraudulent site or risky download.
• Be careful about downloading any software file off the Internet. Adware, malware and viruses frequently “ride in” atop music, video and other files. As a rule of thumb, do not download anything from the Internet unless it is from a trusted source — and even then be diligent, as some trusted companies have utilized adware companies to pitch their products.
• Use anti-adware, anti-malware and anti-virus software religiously. A number of reputable companies offer security software. While most products require a subscription, some excellent software is still free — at least at this point.
• If you are accessing the Internet through a broadband connection, install a router between your computer and your modem. Routers act as an external firewall, hiding your computer’s identification (Internet Protocol address) from would-be intruders.
• Control who uses your computer.
