Guidelines for safe internet usage

E-mail use:

  • Messages should be checked for language errors and coherency. Errors can be indicative of computer-translated spam.
  • Mail from unknown sources, sent from a suspicious address (i.e., and with suspicious titles should be deleted.
  • Correspondence from trusted sources could have been sent against their will, via an infected computer. Suspicious messages and attachments can’t be trusted even when sent from recognised address.
  • Links embedded in email text should never be clicked. Address should be typed into the address bar of the browser by hand.
  • Before opening any attachments, it should be considered whether it is expected and was alluded in the message. Doubts should be verified with the sender.

Using the browser:

  • Before entering a website, address should be checked for typos and suspicious errors (e.g. “microsaft” instead of “microsoft). Sites with suspicious addresses should be avoided.
  • Before logging in on a site check its authenticity. Address should begin with https:// and can’t contain any typos. Suspicious sites might contain warped logos, unexpected ads or other unusual elements.
  • Avoid installing unnecessary browser plugins, additional widgets or accelerators. Necessary and working plugins should be kept updated.

Installing software:

  • Unlicensed programs can provide breaches in system’s security and can result in unauthorised remote access to computer. The most secure source of software is the producers’ website.
  • Many popular software download sites force installation of potentially dangerous download manager.
  • Software installers can have additional install options turned on on default. They might install unnecessary or dangerous software like adware, redundant antivirus software or other.
  • Installed antivirus software should be checked for function and updates. If it turned off by itself or the updates stopped, it should be immediately reported to computer administrator.
  • Keep track of updates and patches for operating system and installed software.

Data safety

  • Important files should be backed up on external memory, and stored in at least 2 copies at secure location.
