Malware infections which are basically derived from the two separate words " malicious " and " software " are harmful infections essentially created to hack into or infiltrate a computer's operating system secretly.

Such features of the system control the stability of your computer system so these infections will attempt to bring down your PC. At present time the most common forms of malware are viruses and worms which are destructive to say the least.
The computer virus infections when executed will force other programs to become infected as they are loaded by the user and they also have payloads which can can do various other malicious and harmful actions to a system. The worm will also hold similar properties and is notorious for its abilities to spread or transfer itself over computer networks thereby infecting many other systems that are available. One other infection worth mentioning is the trojan horse which also is of great concern and risk to a computer system.
Designed to be harmless to the human eye trojan infected programs will affect many computers on a daily basis. Upon activation or execution of the executable of the file or program, malicious scripts will secretly be loaded behind operations and this will consequently corrupt system components and other valuable configurations to which the operating system is controlled by. Because the trojan application itself can often come hidden as a form of spyware it can inject itself into a system easily and unleash problems in no time. Many who suffer from the notorious blue desktop with the words " warning spyware detected on your computer " have been attacked by a trojan.
The root kit allows modification to take place to the computer system in such a way that any infectious malware program will remain or stay concealed which may be in operation. It is a fact that quite a number of malicious infections are able to resist free malware removal tools and other security applications due to their superior structure. To further add to this list of undesirable infections or effects one should also become actively aware of backdoors.

Other malware applications can proceed to install key loggers onto a system and this consequently allows for the capturing and recording of key strokes related to domain passwords, username logins, bank details and any other more personal information. Once taken or stored this data will be sent to the creator who can do with it what he pleases. Another way which infections can waste your money is through dialers which attack internet connections that are on dial up. By dialing expensive numbers they are able to cause high bills for you.

One further infection type which has gone without discussion is spyware. Spyware infections will not behave like the virus or trojan because it is not malicious or able to inflict similar corruption. This tracking software will instead harvest a variety of information about a computer system relating to browser history, information and configurations which are passed onto other people.
