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.

With a decent firewall/security system in place, the chance of getting viruses is dramatically reduced, meaning that the processing speeds stay high and don’t falter due to a virus a attacking them. Also many viruses cause the computer to crash/freeze, this is stopped by the firewall scanning files before you open/download them, and therefore warning you if a virus is found.

 

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.

Secure privacy settings helps you protect personal information, the utility used for this would be partly internet options, where you can delete internet viewing history, and downloads. File passwords also help you maintain good security by restricting access to certain files of your choice, and the computer login also helps you stop people stop accessing your computer entirely, by requesting a password before letting anything work, although there are two ways of accessing files, some done by Trojan horses, a virus planted on some files intended to attack your computer. These are stopped by the firewall.

 

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.

Drive formatting can improve the devices you use with your computer, and helps the computer run smother, with a properly formatted hard drive, you will be able to save and edit files with ease without any problems and notifications asking if you want to format the hard drive, and so on.
