Securing your PC

Install an Anti-Virus program

All users are expected to have an up to date virus scanner installed. If you do not have a virus scanner, McMaster provides one to residence students free of charge. It can be downloaded from http://antivirus.mcmaster.ca. This scanner will only work on-campus and should be installed immediately after connecting to the network.

Run Windows Updates

ALL versions of Windows contain numerous bugs and security flaws. To ensure your computer is up to date:

  • Open Internet Explorer
  • Click on the "Tools" menu
  • Select "Windows Update"
  • Follow the instructions to update your computer.

PLEASE NOTE: In order to fully update windows, you may have to run "Windows Update" repeatedly. The software will inform you when there is no more updates for your computer.

Run a Firewall

Firewall programs can help protect your computer from outside attacks. Windows Xp comes with a built in firewall that will automatically enabled if Windows is fully up to date(see above). For other versions of windows, users can install a third-party firewall. Several free firewalls can be downloaded from the Internet.

Use Strong Administrator Passwords

Numerous viruses exploit computers that have weak or missing passwords on accounts with administrator privileges. To change a password when logged into an account:

  • Hold down ctrl AND alt keys, then press delete
  • Select "change password"

For all other accounts:

  • Open up "My Computer" (found either on your desktop or in your Start menu)
  • Open up "Control Panel"
  • Select "User Accounts"
  • Highlight each account with administrator rights, then click the button "Reset Password".

NOTE: Strong passwords contain combinations of upper and/re lowercase letters and/or numbers and/or symbols.

Run Spyware Removal Utilities

Much like viruses, spyware programs can have negative effects on your computer. Third party programs such as "AdAware," and "Spybot-Search and Destroy" can be obtained from the Internet for free, and can help you scan for and clean spyware from your computer. Microsoft has also released some Beta(pre-release) anti-spyware software. It can be found on Microsoft's website.

Use Alternative Web Browsers

Many viruses and spyware programs specifically target weaknesses found in Microsoft's Internet Explorer. Simply avoiding the use of Internet Explorer for day-to-day browsing activities can significantly reduce a computer's vulnerability. McMaster encourages users to try other web browsers such as Mozilla Firefox (avialable at http://www.mozilla.org) in order to reduce this vulnerability.
