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:

• Only install applications and software from well known companies you trust
• Make sure your computer is cleansed from viruses/spyware and has up-to-date anti-virus and anti-spyware software installed
  
• Keep your operating system and browser up-to-date with the latest security updates and patches

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

• Do not disclose it to anyone (including Kristal employees)
• Use a strong password
  
• Do not use the same password for multiple web applications
• Do not store your passwords near your computer or on your desk where others might easily find them
• Remember to change your Password every 30-60 days. Learn how to choose an Internet Password.
• If you get an email that looks like it's from whom you have an account asking to confirm your password, don't respond until you've checked with the company directly
  
• Do not auto save your passwords
  

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.
