In the base it's not enough to have all updates of system/applications with antivirus but it is necessar to use common sense during surfing on the Internet, where do you click and what do you download/install.

Basic points to secure the computer:

  1. Regular updates of operating system on your computer. If you don't manage the computer or it isn't managed by CIT, contact your faculty/department administrator.
  2. Installed and updated antivirus program.
  3. Installed and set firewall. From Microsoft or in case that you are sufficiently knowledgeable you can use firewall within other antivirus program.
  4. Suitable choice of the password and caution when handling it.
  5. Set the password for admin account.
  6. In Windows Vista check if you have enabled User Account Control (UAC). Go via Start → Control Panels → User accountsy → Your account where click on link Enable or disable UAC and check the choice To protect the computer, use UAC.
  7. Use safe communication protocols SSH, HTTPS (they don't transfer password in open form). For other protocols, e.g. POP3 and IMAP for email, use SSL (Secure Socket Layer).
  8. Higher attention to visited websites, opened links and email messages etc.
  9. Caution when downloading software, application plugins etc..
  10. Many attack are directed to users of MS Internet Exploreru, try to use e.g. browsers (free download)  Mozilla Firefox, Google Chrome or Opera.
  11. Consider change of rights of your account from administrator to user in the group USERS, it will limit application installations but also undesirable software. You can do the change via Start → Settings → Control Panels → User accounts → Your account → Change type of account → choice With limited access.
  12. Regularly do backups of your data for case of reinstalation of the computer. Do the backup preferably to another physicall disk or other media (USB disk, CD/DVD). In case of infection of data and their healing by deleting you will have them in backup.
  13. Educate yourself on computer security, viruses and attack are becoming increasingly sophisticated.
