2. Spyware and other malware

Spywares are malicious programs which run on your computers, chewing up resources and causing damage. These are often used for displaying advertisements (adware) and pop up windows. Other types of spyware collect credit card and other personal information from your computer for stealing your identity. Key loggers are a type of spyware which records all your key strokes and transmits this information often via email.

Signs that your computer is infected with malware:

  • Your home page is changed
  • New toolbars are automatically added in your web browser
  • Your computer becomes very sluggish or crashes.
  • Your computer dials toll calls automatically.
  • You are specially at risk if you visit free music sites or peer-to-peer sharing websites and download files.

Ensure that your antivirus and antispyware programs scan emails as they arrive on your computer.

  1. Provide your primary email address only to people you absolutely trust.
  2. Do not open spam messages. This tells the spammer that your email address is valid.
  3. Ensure spam is directed automatically to Junk email folder, then quickly look at it without opening it (to make sure that any legitimate email is not accidentally labelled as spam), then delete it.
  4. Messages you believe are spam can be informed to your ISP.

6. Firewall

A firewall is a software which identifies and block hackers from accessing your computer, while at the same time allowing you access to information.

  • Ensure that your password contains letters as well as numbers
  • Ensure that your password is not a simple word that can be easily guessed.
  • Immediately change your password if you believe it has become compromised.
  • Remember you are responsible for keeping your password safe.
