Task 5 (D1)
Expand on your notes for Task 3 explaining the purpose of different software utilities to explain how each can improve the performance of a computer system. You need to cover:
- security virus protection and/or firewalls;
- clean up tools for removal of cookies and/or internet history and/or defragmentation;
- drive formatting

Virus Protection: Anti-virus
software is very important in order to keep your computer secure and to a high
performance. Viruses can cause real harm to a computer such as destroying
important data, slowing down a computer or shutting down a computer altogether.
Anti-virus software is used to identify potential threats to a computer system
and block them.
Firewall: A firewall is another form of security that can be added onto a computer. Firewalls act as a barrier to keep harmful software out of a network or a specific computer. They are designed to block or prevent unauthorised access to a network. They work as filters for your network traffic by blocking incoming information that is seen as unsafe. It is very important to make sure that you've got protection from these kinds of things like malicious software.
Clean Up of Cookies: While cookie files are quite small, they can still build up and slow down your system performance. When too many cookies accumulate, those files can cause the system to run a lot slower than it should. It is important to take the time to delete the cookies to increase the speed and performance of computer.
Clean Up of Internet History: Removing all internet history will increase the general performance of a computer; it will be able to run faster because there is less data stored on to the system. It is also useful to do this if you are on a public computer as you can remove all information related to you from the system. This can be extremely important if the information is usernames or passwords.
Defragmentation: Fragmentation makes your hard drive do extra work that can slow down your computer. Defragmentation rearranges fragmented data so your hard drive can work more efficiently. Defragmentation can be done manually or can be set to perform this task to a certain timeline.
Drive Formatting: Over time a computer’s hard drive may experience malfunctions due to wear and tear, viruses, or other programs that slow down and corrupt the computer. To maintain the performance of your PC, reformatting the hard drive every once in a while is a good solution. After formatting a hard drive and reinstalling the operating system, software program glitches and general lag should disappear, and the computer’s performance should improve.
