Unit 2: Task three - 2.1

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.
