If you really want to help protect your self from virus threats, you should ALWAYS keep your computer up-to-date with the latest security patches that become available for your Operating System which is probably Windows.

While it is often difficult to determine the precise cause of your sluggish PC, there are several likely culprits. Over time, the files and folders on your hard disk drive(s) may become fragmented. You should periodically ‘defragment’ your hard disk drives(s) by using a utility program for that purpose. For example, if you are using Windows, the Disk Defragmenter can be found in Accessories, System Tools.

 However, there are many other commercial and open-source utilities with additional features that will keep your file system up to speed. The Windows registry can become fragmented, thereby slowing down your computer. Again, a good utility program can be purchased or downloaded (either as freeware or shareware) to take care of this problem.

Did you know that your system’s memory can become fragmented? There are several specialized programs that will ‘defrag’ your RAM. If your computer seems sluggish, you probably have accumulated a great number of temporary files that can be deleted, in the case of Windows, by using the Disk Cleanup utility in Accessories, System Tools.
