How Viruses Spread

There are many ways for a virus to enter your system:

• Email attachments

• World Wide Web (WWW) sites

• FTP traffic from the Internet (file downloads)

• Shared network files & network traffic in general

• Demonstration software

• Pirated software

• Shrink-wrapped, production programs (rare)

• Computer labs

• Electronic bulletin boards (BBS)

• Diskette swapping (using other people’s diskettes for carrying data and programs back and forth)

The most likely virus entry points are email, Internet and network connections, floppy disk drives, and

modems or other serial or parallel port connections. In today’s increasingly interconnected workplace (Inter-

net, intranet, shared drives, removable drives, and email), virus outbreaks now can spread faster and wider

than ever before.

Virus Writers

In the typical scenario, it is an individual, working alone, who writes a virus program and then introduces it

onto a single computer, network server, or the Internet. Why? Ego, revenge, sabotage, and basic disgruntle-

ment have all been cited as motivations. Recently, do-it-yourself “virus kits” have been popping up on the

Internet, and macro scripts are becoming both easier to learn and more powerful, putting the capacity to

engineer viruses in the hands of nearly everyone. In other words, no single, likely profile exits by which virus

writers can be described or understood.

So whatever the reason one may have for writing a virus, the important thing is to make certain your com-

pany is not victimized, that your data you are responsible for is safe, and that precious time is not wasted

hunting down (and cleaning up after) viruses.
