ICT Coursework EssayVirus, a special program which nates do baneful also annoying subjects, it is a very tricky thing, because there are lots of different computer viruses, near of them might format your hard disk or they buns make copies of itself without the user knowing nearly itetc. they all pick up different behaviours but all of them do things that you may non like to let on to your computer.Before we know how to protect ourselves, we need to know how viruses work. Viruses are very annoying, because they spread. But they are not spreading in a normal way which you heap see they hide in the flush sector of a storage device, and this storage device can either be a floppy disk disk or CD-ROM that youve just borrowed from your friend. After it gets into your computer, it will do what the designer of this virus told it to do, it can be make millions of copies, or format the hard disketc.If so, how can people get away from this thing that you can not see? For the pu zzle like this, people have made those anti-virus programs to find the virus, I strongly recommend you to have an anti-virus program, because you may never know what it actually in the file you are looking.In a PC, if a virus gets in, it will begin to spread it self, and do damage to it. kitty we stop it? Yes, virus has always been a big problem to PCs, and there are many solutions as well, its just whether people actually do it or not. We can like have regular unhurt system virus scan e.g. every week. We can also use the floppy disk or CD-ROM that you trust, but even if you trust the source of it, you will still need to have a virus scan before you open it.Be careful with all the files that you have downloaded from the internet, because you may never know is it a clean file.

Viruses do not only go from storage devices, they can also come form other computers in your network. So if a single computer in your network gets the virus, all the computers on the network are in danger. So again, regular virus scan, be careful with all the files that you get from other placesetc. should help to keep the damage to stripped.For me, I do have those anti-virus programs and I do all the things Ive said above, with the anti-virus program, I think the damage is kept to a minimum but I found a problem, if a virus gets into the anti-virus program it self and changes the configuration of the system, nothing will be known because the anti-virus program it self is the virusHowever, virus has always been a problem for us, but if we do be aware of it, I am sure that the person who made the virus will soon find there is no way of getting a virus into our system. Finally, do never forget a virus can do anything to your computer, things can really go m altreat if you dont keep an eye on you computer.
