Security virus protection/firewalls-
Antivirus or anti-virus software is used to prevent and remove malware, including computer worm, Trojan horses, spyware and adware. The utility prevents downloads of harmful documents by scanning them and warning you of the danger.
Firewalls- A firewall is a device or set of devices designed to permit or deny network transmissions based upon a set of rules and is used to protect networks from unauthorized access whilst letting you access legitimate sites without a problem. Many personal computer operating systems include software-based firewalls to protect against threats from the public Internet.

Clean up tools for removal of cookies and/or internet history and/or defragmentation-
These functions allow you to remove certain aspects of the internet, the sites you’ve visited, downloaded from etc... This enhances the security of the internet and also stops people finding out personal information, defragmentation is a process that reduces the amount of fragmentation. It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of fragments.

Drive formatting-
Format actually means to prepare a storage medium, usually a hard drive, for reading and writing. When you format a hard drive, the operating system erases all bookkeeping information on the disk, tests the disk to make sure all sectors are reliable, marks bad sectors, and creates internal address tables that it later uses to locate information. This means you are able to access the files saved on the hard drive.
