Computer Viruses and Trojan Horses FAQ

What exactly are computer viruses? 

Similar to their biological brothers, computer viruses are designed to propagate, traveling from computer to computer to perform some mischief. That mischief may be as innocent as displaying a message that reads, "This Computer is Stoned," or as fatal as wiping out every file on a hard drive. There are more than 48,000 known viruses, and 1,000 or so are active. 

1. A virus consists of at least two parts: the replication code, which spreads the virus, and the payload, which is the prank or destructive part. Whoever wrote the virus inserts the virus code into an otherwise harmless program. The program -- with the virus -- is distributed through the Internet, on floppy disks, or even on commercial CD-ROMs. 

2. Once you open the host program, the parent virus is activated and replicates even further. The virus spreads copies of itself to other drives on your computer and to other computers on the same network. Each of these child viruses becomes a parent virus and replicates even further. 

3. A virus may remain dormant for months so it can spread without suspicion. It waits for a trigger, often a specific date to launch itself. If an infected computer boots or an infected program is launched under trigger conditions, the rest of the virus activates to deliver the payload. Typically the virus will destroy the boot record or files on your drive that have certain extensions. 

4. Other viruses called worms replicate and spread with great speed. One such worm is an e-mail macro virus, such as Melissa or the Love Bug, which is distributed as an attachment to an innocent-looking message. Merely opening the message to read it activates the macro. A typical macro virus accesses your mail program's address book and sends copies of the infected message to everyone in the book. This begins a chain reaction, with each recipient perpetuating the virus. This in itself can be the macro virus's payload: jamming mail systems with so many messages that the systems are too packed to carry legitimate mail. Other macro viruses destroy files and boot records as well.


What is a Trojan Horse?

This is another danger to your computer. At first glance it will appear to be useful software but will actually do damage once installed or run on your computer.

Those on the receiving end of a Trojan Horse are usually tricked into opening them because they appear to be receiving legitimate software or files from a legitimate source. 

When a Trojan is activated on your computer, the results can vary. Some Trojans are designed to be more annoying than malicious (like changing your desktop, adding silly active desktop icons) or they can cause serious damage by deleting files and destroying information on your system. 

Trojans are also known to create a backdoor on your computer that gives malicious users access to your system, possibly allowing confidential or personal information to be compromised. Unlike viruses and worms, Trojans do not reproduce by infecting other files nor do they self-replicate.
