Information Systems are under greater threat now than they have ever been, not only are attacks becoming more frequent, they are becoming more complex. Whether your network is large or small it is important that every gateway to the outside world is secure.
In-order to protect your systems and keep them running at their full potential the right security measures need to be implemented. We know that the wrong security measures can adversely affect the performance of systems, so we take great care to utilise right tools in the right way.
Macro viruses use features within standard applications, which perform unknown tasks. These viruses are activated each time the file they are attached is opened. They spread very quickly due to the high number of people sharing data.
File viruses attach themselves to programs and can be transferred by disc, file transfer or e-mail attachments.
Boot Sector viruses infect the area of the hard disk that is used when the computer starts up. This means the virus will be activated just by turning on the computer.

Worm viruses are designed to replicate themselves from one computer to another over a network or the internet. They usually drain computer resources, delete data and spread quickly via email.
Trojan Horse viruses disguise themselves as a useful application, but in reality, when activated can cause harm to the computer, such as, loss, damage or theft of data. The main difference between a trojan horse and other viruses is that they do not replicate themselves. “How can I tell if I have a virus?”
Visible symptoms of a virus include loss of files, displaying unwanted messages and sudden declines in computer performance, etc.
One way to know whether your computer has a virus is to scan the machine with an up-to-date anti-virus program. If this program finds a virus, it will tell you the name of the virus and tell you how to remove it, if it does not remove it automatically. It is important to constantly keep anti-virus programs up-to-date; otherwise it will not know how to protect the computer from any viruses that have been developed since the last update.
“What is a Virus Hoax?”
Virus hoaxes are email warning about computer viruses. They are more than likely scare alerts and hold no value to them. Ways to identify a hoax is to check the sender’s address; if the sender is not a reliable source then it is probably a hoax. Virus hoaxes often encourage people to forward the email on.
IN CONCLUSION
Whether your computer is on a network that is connected to the internet, or you are just using a modem for internet or e-mail use, then you are at risk. It is even possible for a stand alone machine to get a virus via floppy disks or some other media.
Some organizations may not even be aware that their machines are infected and the security of their personal information is jeopardised. Depending on the size and structure of your system(s) the solutions can be varied.
To reduce the risk of getting a virus, it is highly recommended to have an anti-virus program on your machine(s); however not all threats can be removed this simply – some require expert attention.
Recently, viruses have become a major concern to IT Managers worldwide. Do your best to make sure your systems are covered from such threats - If not, the damage could be costly and irreversible! |
