The
purpose of different software utilities.
Security virus protection
The main purpose of
antivirus software is to protect the
computer from getting a virus. It does this by scanning downloads and attachments for
viruses and then it also runs in the background when the service user is using
the internet. If a virus was to approach the program then the computer would
alert the service user and give options of getting rid of it before it spreads
across the computer files.
Defragmentation
The purpose of
defragmentation is when a computer
locates all lost
files, it gathers them all
and organises the files that have been fragmented -(when a file has originally
been saved into the incorrect place). This
is a useful device because it allows the computer database to become more
organised and it increases the processing speed overall improving performance.
Drive formatting
This completely wipes the hard drive overall restoring the
computer to the default settings. This is done when the computer is crashed by
a virus or if the hard drive is cluttered with unnecessary files. This can also improve performance
as it allows the system to run faster without risk of virus attacks.
