Malware is another term for malicious software which is programmed by attackers to interfere and gain access your private computer system. It consists of a mixture of scripts, code and other malware which is designed to intrude your privacy. So what does malware actually include?
The most common malicious programs are computer viruses, Trojans and computer worms.
It is extremely common that 9 out of 10 people who own a computer or a laptop will get a virus at some point. This is because many viruses’ can adapt and breach very quickly to the version of the anti-virus software you have installed. The reason behind this is the way
a computer virus works, they are designed to do anything possible to replicate itself
and spread from one computer to another. This is why it is crucial to update your anti-virus software as frequently as possible, due to the fact that malware is advancing on a daily basis.
If you do ever get a virus it is extremely important to disconnect from your network as the virus can send automated messages from your system and these messages could contain private information such as your bank details.
The Trojan horse unlike a computer virus is a non-self-replicating form of malware. It does not go into your computer files and spam other network users instead it gains unauthorized access via a “backdoor” and stays undetected. In summary it is just and unauthorized remote control to your computer system and a hacker can control whatever they want. The controller can install and delete files, crash the computer and even access the webcam of the system!
The best way I can describe a computer worm is that it is more of a network version of the computer virus. They are both designed in a similar way but perform a little bit differently. A computer worm replicates itself but it doesn’t rely on a certain program to cause damage, it relys on security loopholes and failures. The worm almost every single time causes damage the targets computer network even if it just a little damage, which won’t really affect the target.
