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.
