Malware is a pretty uncommon term, and is not familiar to a lot of users of computer software. Basically, the term refers to any kind of software that has been created to cause harm to its host computer by installing things and doing procedures unknown to the user.
Specific examples of malware include spyware and adware, both of which operate by conducting unauthorized operations on a computer. Though malware and computer viruses are different, they are both specifically designed to cause harm to the host computer, as opposed to a legitimate program that you yourself install which does not execute properly. Malware programs are more commonly spread through end user installations, such as peer to peer applications, than through installations from purchased software. Malware most frequently finds its way onto your computer through Trojan horses and rootkits.
Trojan horses,are just as they sound, they are harmful installations that are hidden by seemingly harmless installations. While running these installations seems safe, what the user does not know is that malware is also secretly installing itself at the same time. In order for malware to continue to work, it needs to stay hidden and that is where Rookits come in. Rootkits Make sure that the malware installed on your computer stays completely undetectable, and that it does not show up in your list of system processes.
The more sophisticated kinds of rootkits will actively prevent you from deleting them. It may, for instance, duplicate itself several times, and replace those copies whenever they’re removed, making it difficult to get rid of them all and also harder to identify the original problem files.
Some common examples of malware include Blaster, Sasser, and Mydoom. In addition to these and other versions of malware, there exists another category of unauthorized software, often termed grayware. Unlike malware, grayware does not actually harm your computer ? it is usually merely annoying. Examples of grayware include unauthorized advertisements on your computer and harmless, but nonetheless irritating, joke programs.
These can be quite tiresome and are usually as difficult to get rid of as malware, and therefore are classified along with it. Not only can this software compromise your computers safety, but it can also leave you more vulnerable to other damaging installations. Grayware and malware can also get into your system through codes that are unauthorized by things you plug into your USB ports.
Since it is virtually impossible to keep your system free of malware, you should routinely check for it by using a reputable anti-malware system, such as Microsoft’s Malicious Software Removal Tool. This program — compatible with Windows Vista, Windows XP, Windows 2000 and Windows Server 2003 — can both identify the specific malware installations on your system and assist you in removing them.
