computer data, or preventing the computer from starting up properly.

making appropriate measures is recommended to reduce the risk of virus and other attacks.
Use antivirus software (commercially available).

Do not use disks or programs of unknown origin.

gram to update Windows on your computer to its latest version. This update is also an effective measure for preventing
viruses and other forms of computer attack.
