No matter how you use the internet, it is necessary to follow some basic instructions to ensure that your computer is protected from any new threats. Just as you protect your house with locks and alarms, you must protect your computer with updated antivirus software, regular scans for viruses, a personal firewall and the latest security updates for your web browser and operating system.

To protect your computer, follow these steps:

  • Use antivirus software and update it regularly. This will protect you from the latest viruses. Never download programs from the internet unless you are certain of their provenance.

  • Install a personal firewall. A firewall is a system that protects you against hackers, viruses and worms which try to invade your computer when connected to the internet.

The goal of phishing is deceive the recipients of emails and extort their personal and confidential financial data, such as access codes (username, PIN), credit card numbers, etc.

  • Be very careful not to give information to any email urging you to disclose personal financial data, such as usernames, PIN, credit card numbers, etc. Scam emails are usually addressed to many recipients and will therefore not mention your full name.

  • Always make sure that you are use safe webpages when entering your confidential personal data. The electronic address of safe pages starts with https, instead of http.
