Internet Security

Although there is no such thing as absolute Internet security, there are some basic security mechanisms that can significantly reduce the potential risk.

Since most users have Windows installed, special attention will be dedicated to protecting Windows operating systems.

In order to protect your computer from malicious software, you are encouraged to:

  1. Install antivirus software on your computer.
    Make sure that you choose a reliable antivirus program, able to protect your computer from malicious programs such as viruses, trojans, spyware, and other malicious software installed without your knowledge.
    Viruses are easily spread via e-mail messages and through exchange of programs with other people. These programs can delete or modify important data on your computer and even delete the entire contents of your hard disk. After you install an antivirus program, remember to also update virus definitions. Otherwise, your computer will be as vulnerable as before.
    Note: Individual users of our ADSL service are granted a free license for Kaspersky AV Personal 2009.
  2. Take necessary precautions when opening email messages with unknown sender, especially if the message contains an attachment. Remember to scan every email attachment with the updated version of antivirus software.
  3. If you don't have a hardware firewall, install a reliable network firewall on your computer or at least enable your default OS firewall.
    If your firewall is running when you're online, it will monitor and block the flow of data between the Internet and your computer in case it detects unauthorized access to computer. Firewall prevents and informs you abut any such attempts.
  4. Get the latest updates and security patches available for your computer's operating system via Windows Update.
  5. Networks and File and Printer Sharing (Control Panel – Networks) in Windows may allow misuse of data located on your computer.
    If you have no need for sharing files over a network, delete Microsoft Networks and File and Printer Sharing. Exercise extreme caution if you want to enable file sharing over your network, especially if you are connected to the Internet.

Tips for selecting a password

We strongly encourage you to change your password (for logging into the system, email, etc.) relatively often, for example once in every few weeks.

Of course, as these passwords are made public, they no longer present a good example.
