The good news is that many technology devices in a classroom are immune to computer viruses. These nasty e-bugs do not affect equipment such as data projectors, scanners, printers or interactive whiteboards. It is mainly your laptop or computer that is at risk.
The bad news is that when your computer is infected by a virus, other peripherals – devices attached to your computer – may not function since they receive their instructions from the computer.
It is quite simple to safeguard your classroom technology against virus attacks: you only have to protect your computer or laptop. How can you do this?
During a flu epidemic you protect yourself by staying away from people who are infected. The same principle applies to a computer virus. You won’t pick up a virus on your computer if you put your machine next to an infected one. But you can catch a virus if you communicate with an infected machine. This can happen over the internet, through an e-mail message, or by means of a data stick or disk that has been infected by another computer.
One of the common ways in which viruses are transferred is through e-mail attachments. If you do not know the source of an e-mail, or if it seems suspect, delete it from your system without opening the attachment.
Don’t use a data stick or disk unless you have confidence that the previous user of the disk is not infected by viruses. You can never be sure – always view unknown sources of data with suspicion.
You also need some preventative medicine – in the form of anti-virus software – in the same way as you would go for an anti-virus injection to boost your body’s immunity. If your school does not have a site licence for this software, it can be obtained from technology vendors; free anti-virus programs are also available on the internet.
New strains of biological viruses develop all the time and that is why you must get anti-virus booster injections. Similarly, since new computer viruses are developed on an ongoing basis, virus fighters frequently add antidotes to newly discovered viruses in their anti-virus software programs. To benefit from them, you must update your system regularly with the latest version of the program. Your licence usually allows you to load these updates from the internet.
Adequate protection against computer viruses is in your hands.
