Scams

Protect your computer from malicious software

Various sorts of malicious programs such as viruses, worms and spyware are afoot on the Internet. Malicious software usually spreads through junk mail, but also through files attached to apparently ordinary e-mails.

Malware can

  • slow down and disrupt computer function, by shutting down in the middle of work, for example.
  • steal files from a computer.
  • monitor a user's activities on the computer. A program can copy all keystrokes, for example, and transmit the information to the malware sender, who may thus obtain user names and passwords.
  • direct a customer's online bank transfers to the wrong accounts without the customer noticing.Malware can also spread to mobile phones. It can then send messages to numbers saved on the user's phone, for example. Malware on mobile phones will become increasingly rare in the future, however, as new operating systems for phones are developed.

Security tips

  • Do not open e-mail attachments unless you are absolutely sure what they are.
  • Do not reply to junk messages. Your reply will indicate that your address is in active use and may lead to more junk mail in the future.
  • Check that everything is in order with the data protection software and settings on your computer, such as the anti-virus software and firewall. Your web browser may already be equipped with safety features. You can look for them under the Tools or Help menus. Free software to prevent data security problems may also be included with your operating system. Software can also be downloaded from software company websites, or bought in computer stores.
  • Familiarize yourself with the instruction manual accompanying your mobile phone and use the security settings.
  • Update data security software and settings regularly. Find out if program updates are automatic or if you have to download the newest version from the software company website, for example.
  • If you don't use your computer for a long time, shut it down and disconnect it from the network. Then the computer will not receive or send information over the Internet, and will be safe from outside attacks.
  • Do not use predictable passwords. A password should have at least eight characters and include letters, symbols and numbers. Avoid recognizable words.
  • Change your password regularly. If possible, use a different password when doing business with different entities.
  • Do not reveal your user names or passwords on the Internet, via e-mail or on the phone. Do not store them in a highly visible place, either.
  • Make back-up copies of your most important files and keep them in a safe place.
  • If you suspect that your computer is infected by a virus or has had a security breach, disconnect it from the network immediately. Scan the entire computer with up-to-date anti-virus software and also update the firewall.
