What Is A Computer Virus

While There Is No Widely-Accepted Definition Of The Term Computer Virus
The Following Loose Definition Should Be Enough:


A Computer Virus Is An Executable Code That, When Run By Someone
Infects Or Attaches Itself To Other Executable Codes In A Computer
It Does This In An Effort To Reproduce Itself
Some Computer Viruses Are Malicious, Erasing Files Or Locking Up Systems
Others Merely Present A Problem Solely Through The Act Of Infecting Other Codes
In Either Case, Though, Computer Virus Infections Should Not Go Untreated

Closely Related To Computer Viruses Are Trojan Horses And Worms
A Trojan Horse Is A Program That Performs Some Undesired Yet Intended Action
While Or In Addition To, Pretending To Do Something Else
One Common Class Of Trojans Are Fake Login Programs
They Collect Accounts And Passwords By Prompting For The Information
They Work Just Like A Normal Login Program Does
Another Is A Disk Defragger That Erases Files Rather Than Reorganizing Them
A Trojan Horse Differs From A Virus
In That The Former Does Not Attempt To Reproduce Itself
A Worm Is Just A Self-Propagating Virus

Viruses Come In Many Shapes And Sizes, Such As

File Infectors

These Viruses Attach Themselves To Regular Programs
Such As Com Or Exe Files Under Dos
Thus They Execute Each Time The Infected Program Is Run

Cluster Infectors

They Modify The File System So That They Are Run Prior To Other Programs
Note That, Unlike File Infectors, They Do Not Actually Attach Themselves To Programs

Macro Viruses

Word Processing Documents Can Serve As Sources Of Transmission For Viruses
They Take Advantage Of The Auto-Execution Macro Capabilities In Products
Such As Microsoft Word Simply By Opening An Infected Document
The Virus Written In A Product's Macro Language Can Spread

System Infectors

Computer Operating Systems Typically Set Aside A Portion Of Each Disk For Code To Boot The Computer
Under DOS, This Section Is Called A Boot Sector On Floppies
Or A Master Boot Record (Mbr) For Hard Disks
System Infectors Store Themselves In This Area
And Hence Are Invoked Whenever The Disk Is Used To Boot The System
A Virus Must Be Executed By Someone, Perhaps Unwittingly, In Order To Spread, Period

Some Ways In Which This Occurs Include

Booting From An Infected Floppy

System Infectors Are Loaded Each Time An Infected Disk Is Used To Boot The System
This Can Happen Even If A Disk Is Not Equipped With The Files Needed To Truly Boot The Computer, As Is The Case With Most Floppies
With PCs, The Initial Infection Typically Occurs When Someone Boots
Or Reboots A Computer With An Infected Floppy Accidentally Left In Drive A
It Is Always A Good Habit To Check
And Remove Any Floppies That Might Be In The Drives Before Rebooting Your Machine

Running An Infected Program

As Programs Infected With A File Infector Are Run The Virus Spreads
For This Reason You Should Regularly Scan For Viruses
Scan Any Programs You Retrieve From BBS, The Net, A Colleague, Etc.
There Have Been Instances Of Commercial
Shrink-Wrapped Software That Has Been Infected With Viruses!


Some Common Symptoms That Your System Might Have Been Attacked

Your System Has Less Available Memory Than It Should
Unusual Messages Or Displays On Your Monitor
Unusual Sounds Or Music Played At Random Times
A Disk Or Volume Name Has Been Changed Or Renamed
Programs Or Files Are Suddenly Missing Or Fragmented
Unknown Programs Or Files Have Been Created
Some Of Your Files Become Corrupted Or Suddenly Don't Work Properly
Your System Becomes Unusually Slow!

First, Don't Panic And Make The Situation Worse

In Many Cases The Odd Things Computers Do Are Blamed On Computer Viruses
Especially If No Other Explanation Seems To Make Sense
However, In Most Cases
When An Anti-Virus Program Is Used To Check, No Virus Is Actually Found
So, Unless You Have Checked And Confirmed That A Virus Is Actually Present

Don't Panic
It's True That Some Viruses Can Cause:

Unusual Screen Displays Or Messages
Slower Operation Of The Computer Drives To Be Accessed Unexpectedly
And The Drive's Light To Go On
Or A Reduction In The Amount Of Memory Normally Shown For The System
But Even Such Strange Behavior Can Be Caused By Legitimate Software
Harmless Prank Programs Or By Hardware Faults

I Was Having Trouble With My Computer
So I Called Rick The Computer Guy To Come Over
He Clicked A Couple Of Buttons And Solved The Problem
He Gave Me A Bill For A Minimum Service Call
As He Was Walking Away, I Called After Him
"So"
"What Was Wrong?"
He Replied
"It Was An ID Ten T Error"

I Didn't Want To Appear Stupid
But Nonetheless I Inquired
"An ID Ten T Error?
What's That In Case I Need To Fix It Again?"

Rick, The Computer Guy Grinned
"Haven't You Ever Heard Of An ID Ten T Error Before?"
"No," I Replied
"Write It Down" Rick Said
"I Think You Will Figure It Out"
So I Wrote It Out
"I D 1 0 T"
