Computer worm is a malicious computer program that is able to replicate itself and to send out its own replications to other computers. It is able to reproduce itself and thus able to spread on its own.
What is the most common way of getting infected with a computer worm? How does it work?
The most common way your computer can be infected with a worm is through a malicious e-mail attachment, an infected web page, or an infected file. Once this program gets to your computer, it will start spreading through your computer network. More precisely, it will start making copies of itself and sending out these copies to other files of yours or to other devices in your network.
How to prevent attack, how to recognize the infection and how to get rid of it?
A computer worm usually slows down your computer or your network connection because it takes a considerable amount of your computer performance or network capacity. However, a slow computer or a slow connection does not automatically mean that your computer is infected with a worm, it can simply be caused by some other “normal” software.
The best way to detect a worm and to protect yourself against infection is to have a good antivirus in combination with firewall. However, what is absolutely crucial is the caution of users. It is important to be careful when opening suspicious emails or files from unknown sources.
