Malware is still a fairly unfamiliar word to many computer software end users. Put simply, the term refers to software that is created to harm the host computer or to carry out unauthorized installations and procedures without the user?s consent.
Malware also refers to spyware and adware that does sneaky operations on a computer. Malware is different from viruses. A genuine program that you install which doesn’t run properly because of it?s defects is not malware. Malware programs are more often found in installations that users do themselves, such as messengers, than in installations from software you purchase. Some of the most universal ways that malware installs itself on to your computer is through Rookits and Trojan horses.
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.
Advanced Rootkits will also fight any attempt at removing them. For example, a malware program may create instantaneous ‘ghost’ versions of itself, and whenever it realizes that one of the ‘ghosts’ has been deactivated or deleted, the original program quickly begins creating replacements for the deactivated or deleted files in order to protect itself.
Some of the commonly known malware installations include Blaster, Sasser, and Mydoom. Another kind of unauthorized and harmful software that is similar to malware has been termed grayware. Unlike malware, grayware is not harmful, and is usually just very very irritating. Grayware is basically just an annoying software that really works to bug you more than to harm your computer, it installs things like unauthorized joke programs and ads in order to accomplish this goal.
Even grayware, though technically non-malicious, can be difficult to remove and almost equally disruptive to effective use of the computer, so it is often lumped in with malware. Grayware can also unintentionally compromise your computer’s safety and open up your network to worse things like actual malware. Malware and grayware are able to infect you through your USB ports as well as through the internet, and through your general admin network.
While you should always use basic measures of caution to prevent malware from getting on your system in the first place, sometimes things slip through anyway. Therefore you should habitually scan your system for malware and related unpleasant programs by using anti-malware scanners. There are a lot of free programs available online to do this if your finances are tight. But if you want top security you’ll have to pay a little for it, and it’s worth it to get a quality product with regular database updates to keep your system safe from the latest in malware.
