Utility applications
Operating systems may include utility applications which are small
programs designed to improve system performance.
Here are some examples of
utility applications:
Disk defragment – These make hard disks run faster. When you delete a
file it makes a gap on the hard drive which can be reused when another file is
saved. If the new file is too big it fragments to another gap which eventually
makes loading files slower. Defragmentation rewrites files and brings them
together to make the hard disk run faster.
Software firewalls – These stop unwanted traffic from the internet
entering the computer.
Anti-virus software – this tries to prevent malware from entering the
computer, it also scans the computer and connected devices making sure no
malware has gained access.
Note from author:
I would recommend using Microsoft security essentials, it is free and does the job perfectly.
