Computers provide excellent resources and capabilities for millions of users around the world that are not presented in any other technology. Computers require extensive maintenance, however, and begin to exhibit many different problems when not taken care of properly. Computers must be cleaned virtually and physically in order to keep the computer at an optimal performance. By using the following programs and performing the tasks written out below, the user will be able to increase the overall processing speed of their computer, increase virtual memory, and avoid expensive computer repair costs.

CCleaner
CCleaner is a free tool for Windows that combines several features that enhance the overall quality and performance of any computer. CCleaner features a disk cleaner that erases unused files in order to free up wasted memory, a privacy tool that erases the user's online history, temporary files, recent documents, log files, and recycle bin, and a registry cleaner that can replace missing or corrupted files with a fresh copy. CCleaner only takes a few seconds to improve the quality of the user's computer and can be found at http://www.filehippo.com/download_ccleaner/ .How to clean my computer

Spyware Terminator
Spyware Terminator is a free antispyware and antimalware solution that is capable of detecting and removing trojans, worms, keyloggers, and more from the user's computer. Spyware Terminator is able to scan either a designated portion of the user's computer or the entire hard drive. The program features a real-time shield, browser-based protection, and an event scheduler for both scans and updates. The Spyware Terminator threat database is updated on a daily basis but requires that the user update his/her program in order for changes to take effect. Spyware Terminator can be downloaded from http://www.spywareterminator.com/ .

Disk Defragmenter
Disk Defragmenter is a program that ships with all Windows Operating Systems and is designed to improve the overall processing speed of the user's computer. Disk Defragmenter works by rearranging strands of data stored on the hard drive so that there are no gaps in information. By using this technique, the computer is then able to read one continuous line of data to find specific information instead of searching random locations. This significantly decreases the amount of time that the computer spends searching for information and improves overall system performance.

Cleaning the Chassis
When cleaning the exterior of a computer, the chassis is the most important step. This is because the chassis usually collects much more dust and debris than other computer parts. Before proceeding to clean the chassis, the user should turn the computer off and disconnect the power cord from the back of the chassis. The user should then remove the side panel of the chassis and gently wipe the inside with a duster or rag. The user can also purchase compressed air and spray it in between the hard-to-reach places such as behind the hard drive, near the fan, and inside exterior ports and trays. When the majority of the dust has been removed from the chassis, the user should then replace the side panel. It is now safe to turn the computer on if the user wishes to do so.

Monitor Maintenance
After the chassis has been cleaned, the user should proceed to cleaning the monitor. The monitor may collect some dust around its bottom and rear but mostly collects spots and stains on the screen itself. The screen can be cleaned with any window or lens cleaner such as Windex or eyeglass cleaner. The user should wipe the screen in the same direction and avoid leaving additional residue on the screen. The hard plastic that makes up the rest of the monitor can be cleaned with any cleaner including soap and water. The user should, however, unplug the monitor before cleaning the rear and should avoid getting any liquid inside of the monitor's vents.

Cleaning Accessories
Computer accessories such as the keyboard and mouse can be cleaned with a damp rag or paper towel. When cleaning a keyboard, the user should gently press down on each key and scrub the sides of it in order to remove any dust or residue. The user should avoid getting excessive amounts of water in the keyboard but small amounts should not hurt it. The mouse can be cleaned in the same manner. If the mouse includes a rubber ball, the ball can be removed for cleaning purposes by twisting the circular piece that holds it in place.
