A while back I thought my computer had a virus so i had to take it in and pay to get my computer cleared. It would have been nice to know how to fix the problem myself.
The reason i want to learn this is because if my computer starts running slow due excessive files andprogrms I want to be able to do this on my own when the time comes
This topic was chosen because when you download files to your computer, Windows does not always place all the files together. De-fragmenting your disk volume arranges files (and free space) in an orderly manner, reducing the time taken to read a file.
