If the computer slows down there initial reaction is that the computer is infected with a virus. Though, this is true but not all the time. It may be as simple as there are programs that are running in the back ground that should not be and many more. Here are the main reasons why the computer slows down and how to deal with it:
1.    Sectors on the hard disk that is not used, which makes storing new files difficult. This will relatively slow down the computer because it will have a hard time looking of for a good sector to store information. You may defrag the computer once in a while. Twice a month is good. All you need to do is start the Disk Defragment tool and choose driver you want to defrag.

2.    Corrupted files. It can also result to the computer crashing which makes it difficult for the computer to shut down. You can use the Scan Disk tool to search for files that are not being used in the computer and that are safe to delete.
