Viruses self-replicate within computers and across networks and
alter files or data. They usually require some action on the user's part to start, most
often just clicking an executable file attachment on an e-mail (although embedded
programming in an email message can execute a virus program). Typically, people think that
the file came to them from a trusted source or is something they want to see.
Worms are a virus variant that can infect a computer without any
user interaction. A worm doesn't alter files, but resides in active memory and duplicates
itself. Worms use parts of an operating system that are automatic and usually invisible to
the user. It is common for worms to be noticed only when their uncontrolled replication
consumes system resources, slowing or halting other tasks.
Trojans are malicious coding hidden within innocuous programming
or data in such a way that it can get control and do its chosen form of damage, such as
ruining the file allocation table on your hard disk. A Trojan horse may be widely
redistributed along with a virus.
Spyware is programming that is put into your computer to secretly
gather information and relay it to advertisers or other interested parties. Spyware can get
into a computer as a software virus or as the result of installing a new program. Although
not malicious in intent, spyware is often installed without your consent and even without
your knowledge, as a drive-by download or as the result of clicking some option in a
deceptive popup window. By the same token, adware, which usually includes spyware
components, can also be considered malware.
Adware is any software package which automatically plays,
displays, or downloads advertising material to a computer after the software is installed
on it or while the application is being used.
Browser hijackers are programs that alter your computer's browser
settings so that you are redirected to Web sites you had no intention of visiting. Most
browser hijackers alter default home pages and search pages to those of their customers,
who pay for that service because of the traffic it generates. More virulent versions often
add bookmarks for pornographic Web sites to the users' own bookmark collection, generate
pornographic pop-up windows faster than the user can close them, and redirect users to
pornographic sites when they inadvertently mistype a URL or enter a URL without the www.
preface. Poorly coded browser hijackers - which, unsurprisingly, are common - may also slow
your computer down and cause browser crashes.
A Rootkit is a program designed to take fundamental control of a
computer system, without authorization by the system's owners. Typically, rootkits act to
obscure their presence on the system through subversion or evasion of standard operating
system security mechanisms. Often, they are also Trojans as well, thus fooling users into
believing they are safe to run on their systems.
