  20. 20. 24 Updates-sometimes called patches-fix problems with your operating system (OS) (e.g., Windows XP, Windows Vista, Mac OS X) and software programs (e.g., Microsoft Office applications). Most new operating systems are set to download updates by default. Be sure to restart your computer after updates are installed so that the patches can be applied immediately.
  21. 21. 25 To avoid computer problems caused by viruses, install and run an anti-virus program like Norton,Quick Heal,etc. Periodically, check to see if your anti-virus is up to date by opening your anti-virus program and checking the Last updated date. Anti-virus software removes viruses, quarantines and repairs infected files, and can help prevent future viruses.
  22. 22. 26  Don't give out financial account numbers, Social Security numbers, driver’s license numbers or other personal identity information unless you know exactly who's receiving it. Protect others people’s information as you would your own.  Never send personal or confidential information via email or instant messages as these can be easily intercepted.  Beware of phishing scams - a form of fraud that uses email messages that appear to be from a reputable business (often a financial institution) in an attempt to gain personal or account information.

Microsoft Vista and Mac OSX have built-in firewalls.  Once your firewall is turned on, test your firewall for open ports that could allow in viruses and hackers.  Hackers search the Internet by sending out pings (calls) to random computers and wait for responses. Firewalls prevent your computer from responding to these calls.
