Computer virus
What is virus….?
This is a type of program which has
been put together with the aim of causing problems to your computer. Either
your hard disk could permanently damage or at least some of files will be
corrupted.
What can I do to prevent this?
Many computer systems have
anti-virus programs already included if not one should be bought and installed.
One of the most well-known manufacturers of these programs is Norton which has
programs such as McAfee that does excellent job of tracking and destroying
most of viruses.
What should I do if the computer
freeze?
If the mouse no longer
functions, the keyboard appears locked or the screen simply turns black, you will
need to reboot (that it means start up the computer again).
This time, though, do not press
on the button on the tower, instead simultaneously press ctrl+alt+delete. You will be asked if
you want to stop current task, yes and the system will start up again and
return to the desktop.
