Secruity
Security is needed to stop malicious malware/viruses from harming your computer. An example of security software is Norton-Antivirus. The security programs stops the virus from executing a malicious file/code to steal personal information and deleting personal files. Most operating systems also have a firewall built in.
There are many different security systems used to prevent viruses Examples of Anti-Viruses are : Mc Afee, Norton Anti Virus, AVG.
Firewalls are used to prevent other internet users from accessing private networks that can lead to your computer system being hacked and fraud. The firewall will block people who aren’t allowed on the system.
Firewall
Firewalls are used to prevent other internet users from accessing private networks and documents which can lead to your computer system being hacked and fraud.
The Firewall can be turned off but the system will advise you do not turn it off becuase it will make the system more vunerable to viruses and intruders.
The picture shows "Windows Firewall with Advanced Security" on Windows 7. As you can see I have customised what I want to block and turned on my firewall. It is also overlooked by Norton Ant-virus which I have installed on my computer which also has a firewall and custom settings which secure my computer.
An example of a Firewall Software is ZoneAlarm. It blocks viruses that anti-viruses miss, stops and detects hackers trying to break into the users computer. It makes securing the users computer faster and easier than normal firewalls (Windows Firewall) . It is also powered by DefenseNet cloud service which is linked a server elsewhere so users using this firewall software do not get disturbed by unnecessary alerts. You can also customise the settings, what to turn on/off or what time to turn off etc .
Clean-up Tools
Over time, unused files can build up and take up space on your hard-drive. Clean up tools typically delete files which are no longer needed. This is done by de-cluttering and deleting the files such as temporary files which are used by web-browsers to store data to speed up accessing a webpage. It also deletes files that are in the recycle bin, removes old installed programs no longer in use, deletes downloaded program files and removes unwanted toolbars.
An example of a Disk Clean-up Software is Wise Disk Cleaner 3. It will detect what files are taking up a lot of space and give you the option to delete it and it will delete all the cookies and temporary files that take up memory. The programme can be set to run in auto-mode so it will automatically open when it detects there is low space and you can set it to open specific times. either daily, weekly, monthly or when memory is running low. This can improve performance of the computer system .

Defragmentation
Defragmentation of the hard drive basically means to sort the contents of the hard drive into regions of similar files to free up block spaces. It allows files to have their own sections so that they don't waste any unused block spaces.
An example of a Defragment programme is Auslogics Disk Defrag is one of the best defragmentation programmes as it allows multiple disks or individual folders or files to be defragmented. It also allows you to set a specifically priortise the programme and it can also be set so when the defragmentation is done the computer will automatically switch off.

Disk Formatting
Disk formatting is the process of preparing a hard disk or other storage medium for use, including setting up an empty file system. A variety of utilities and programs exist for this task.
An example of a Disk Formatting software is Active @ KillDisk which detects and displays information about all partitions, hard drives and USB's, Wipes out USB/ hard drives completely by secure overwriting data. It detects FAT,FAT32,NFTS files on the drive and will erase using low level disk access.
