|Anti Virus Software Frequently Asked Questions
What is Anti-Virus Software?
Antivirus software (or "anti-virus software") is a class of program
that searches your hard drive and floppy disks for any known or
potential viruses. The market for this kind of Anti-Virus software
has expanded because of Internet growth and the increasing use of
the Internet by businesses concerned about protecting their computer
2. What is Computer Viruses ?
In computers, a virus is a program or programming code that replicates
by being copied or initiating its copying to another program, computer
boot sector or document. Viruses can be transmitted as attachments
to an e-mail note or in a downloaded file, or be present on a diskette
or CD. The immediate source of the e-mail note, downloaded file,
or diskette you've received is usually unaware that it contains
a virus. Some viruses wreak their effect as soon as their code is
executed; other viruses lie dormant until circumstances cause their
code to be executed by the computer. Some viruses are benign or
playful in intent and effect ("Happy Birthday, Ludwig!")
and some can be quite harmful, erasing data or causing your hard
disk to require reformatting. A virus that replicates itself by
resending itself as an e-mail attachment or as part of a network
message is known as a worm.
3, What is Spyware ?
Spyware is any technology that aids in gathering information about a person or organization without their knowledge. On the Internet (where it is sometimes called a spybot or tracking software), spyware is programming that is put in someone's computer to secretly gather information about the user and relay it to advertisers or other interested parties. Spyware can get in a computer as a software virus or as the result of installing a new program.
4. What is Adware ?
Generically, adware (spelled all lower case) is any software application
in which advertising banners are displayed while the program is
running. The authors of these applications include additional code
that delivers the ads, which can be viewed through pop-up windows
or through a bar that appears on a computer screen. AdWare is also a registered trademark that belongs to AdWare Systems, Inc. AdWare Systems builds accounting and media buying systems for the advertising industry and has no connection to pop-up advertising, spyware, or other invasive forms of online advertising.

5. What is Trojan Horse Virus ?
In computers, a Trojan horse is a program in which malicious or harmful code is contained inside apparently harmless 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. In one celebrated case, a Trojan horse was a program that was supposed to find and destroy computer viruses. A Trojan horse may be widely redistributed as part of a computer virus.

6. What is POP-Up ?
A pop-up is a graphical user interface (GUI) display area, usually
a small window, that suddenly appears ("pops up") in the
foreground of the visual interface. Pop-ups can be initiated by
a single or double mouse click or rollover (sometimes called a mouseover),
and also possibly by voice command or can simply be timed to occur.
A pop-up window must be smaller than the background window or interface;
otherwise, it's a replacement interface.

7. What is Worm Virus ?
In a computer, a worm is a self-replicating virus that does not
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.

8. What is Spam ?
Spam is unsolicited e-mail on the Internet. From the sender's point-of-view,
it's a form of bulk mail, often to a list obtained from a spambot
or to a list obtained by companies that specialize in creating e-mail
distribution lists. To the receiver, it usually seems like junk
e-mail. It's roughly equivalent to unsolicited telephone marketing
calls except that the user pays for part of the message since everyone
shares the cost of maintaining the Internet. Spammers typically
send a piece of e-mail to a distribution list in the millions, expecting
that only a tiny number of readers will respond to their offer.
Spam has become a major problem for all Internet users !
9. What is Firewall ?
A firewall is a set of related programs, located at a network gateway
server, that protects the resources of a private network from users
from other networks. (The term also implies the security policy
that is used with the programs.) An enterprise with an intranet
that allows its workers access to the wider Internet installs a
firewall to prevent outsiders from accessing its own private data
resources and for controlling what outside resources its own users
have access to!
