Use a personal firewall

A personal firewall protects your computer against unauthorized access.

Beware of malware infection with drive by download

Drive-by downloads may happen when visiting a malicious or vulnerable website, viewing an email message or by clicking on a deceptive pop-up window. Malware is malicious software installed on your computer which has a harmful intent that can, for example, capture your login password, and other personal data. Examples of malware include software such as spyware, adware, viruses etc. The best way to protect yourself from malware is to exercise caution before installing programs on your computer or opening email attachments. Here are some precautions that are important to take:

Install anti-virus, anti-spyware and malware detection software

The best defense against computer attacks is preventive software. You will need to update the software regularly to guard against new risks, so download updates from your provider as soon as they're available. Or better yet, set the software to update automatically.

Use a pop-up blocker

Set your browser preferences to block pop-ups - aside from being annoying, these pop-ups can contain inappropriate content or have malicious intentions.

Secure your password

Secure wireless networks

Networks in Internet Cafes, hotels and libraries are usually not secure and are easy to tamper with. Even if they provide you with a password, that does not guarantee a secure connection. You should avoid using public computers for online transactions.

Public or shared computer for personal transactions

Anyone who uses the computer after you and visits the same websites can sign on to your accounts. After you sign off, select the option to "Remove a user", if that option is available. Also, make sure to clear the Internet history and any cookies stored.
