What Is Malicious SoftwareBy Paul Edwards |
|
There is often confusion about some of the terms we use to describe malicious software, or malware. Some basic explanations should help to dispel any confusion:
Malware is the generic name given to any kind of software that attempts to steal, damage or destroy the data on your computer. This includes viruses, Trojans, spyware, adware and anything else that computer users consider dangerous or annoying! If you're not sure what each kind of software does, a brief explanation might help...
Viruses tend to destroy the files on your computer. They can damage the files needed to run the computer (like parts of Windows) or can infect data files, like wordprocessing documents.
Trojans disguise themselves as useful programs in order to prevent people from becoming suspicious. Once installed, they allow people to steal confidential information, like passwords. Some Trojans allow people to take control of your computer so that they can send out spam e-mail (making it look as if it comes from you) or do other underhand things.
Adware tends to display annoying advertising messages all of the time. It can also hijack your Internet browser, forcing lots of windows to open up or directing you to certain web sites. Adware is usually considered annoying rather than harmful... unless it has some of the charactertics of spyware.
Spyware gathers information about the way you use your computer and sends it to a third party. Often, the information is used to target advertising but it can also be used for other purposes, like attempts at fraud. |
