Malware is a name that is derived from malicious software. Computer malware is therefore software that is used to interrupt computer operation; it does this through gathering sensitive information and getting access to private computer structures.
The malware is mainly used to work against the needs of the computer user, it is purely meant to cause harm to the computer intentionally. The software steals information and also used to spy on the user as he conducts his operations on the computer without his knowledge.
Computer malware is harmful software which comes with viruses, ransomware, Trojan horses, spyware, scareware and adware and many other hostile programs which are harmful to the computer. These malware are fixed in good files in the computer. While other malware like the spyware are normally entrenched in programs that are supplied by official companies which can always be downloaded from main websites that are always seen to be useful, but these can have extra hidden tracking roles that collects marketing data.
The computer malware was started as pranks but are now widely used by governments and black hat hackers who use it to gather and collect private information that they can use or even disrupt programs that are run by their competitors. Malware is also widely used to work against corporate and government websites to get protected information and sometimes to interrupt their programs and operations.
Computer malware can also be used against individuals to get access to personal information like bank passwords, personal identification, credit card numbers and other personal information. The computers which are at risk are those personal computers that are not well guarded and also those networked computers. It is therefore important to keep personal computers well protected, by use of firewall or any other available protective measures. When using networked computers you can use passwords on protected files so as to try and reduce chances of getting malware attack.
The most widely known and used malware are computer viruses and worms, may be because they are easily spread. Computer viruses are found in the computer operating system and can also be fixed in performing and operational programs, and usually fixed without the permission or consent of the user, and when it is running it spreads to other available programs in the computer. This therefore means that once the computer has been infected by virus malware, it will soon be fully infected if it is not dealt with early enough.
On the other hand, worms act alone and are normally found in a network where it transmits itself to affect other computers. This means that the user will not necessarily have to run a program for the worm to spread as it does in viruses, worms will automatically spread themselves, thus making it more deadly than viruses.
These computer malware can be cleaned out of the system once detected. They can be detected through many ways. For example, when a computer is infected by virus, it may become slow to open and also when running programs. It is important that the user installs software that can protect against any form of malware.
