A very stupid habit. Do I poke you in the face when I’m showing you something? This will induce dead pixels and image persistance. L.C.D. stands for Liquid Crystal Display. It is liquid and crystals (like in a calculator screen). You know how with a calculator, if it gets crushed the 8 looks like an E. Pressing any pressure that is more than about 8 oz, can cause permanent damage to the L.C.D. panel. Care must be taken to not let anyone touch the screen surface. The front surface of the screen is also very easy to scratch, since it is like a plastic in its characteristics.
Remember, screens are for viewing not for touching. Use the mouse pointer not your finger.

What are Computer Viruses?
Computer viruses are programs written by “mean” people. These virus programs are placed into a commonly used program so that program will run the attached virus program as it boots. A virus is inactive until you execute an infected program or application OR start your computer from a disk that has infected system files. Some viruses are programmed specifically to damage the data on your computer by corrupting programs, deleting files, or even erasing your entire hard drive. Many viruses do nothing more than display a message or make sounds / verbal comments at a certain time or a programming event after replicating themselves to be picked up by other users one way or another. Other viruses make your computer’s system behave erratically or crash frequently. Once in memory, one of a number of things can happen. The virus may be programmed to attach to other applications, disks or folders. It may infect a neighbor computer within the network.
The Autorun.inf threat
Autorun.inf is the primary instruction file associated with the Autorun function. Autorun.inf itself is a simple text-based configuration file that tells the operating system which executable program to start. AutoRun is intended as a convenience feature: software distributed on a disc can automatically start an installer when the disc is inserted. Worst is, Autorun can pose a security threat, when the user does not expect or intend to run the software, such as in the case of some viruses, which take advantage of this feature to propagate, especially on USB flash drives.
If you have this problem you can contact me anytime.
So, we will scan first your Flashdrive, Memory Cards or any kind of Removable devices before you can use it on our machines.
