Preface

What happened?

If you’ve ever lost important files stored on your hard disk, watched in dismay

as your computer ground to a halt only to display a prankster’s juvenile

greeting on your monitor, or found yourself having to apologize for abusive

e-mail messages you never sent, you know first-hand how computer viruses

and other harmful programs can disrupt your productivity. If you haven’t yet

suffered from a virus “infection,” count yourself lucky. But with more than

50,000 known viruses in circulation capable of attacking Windows- and

DOS-based computer systems, it really is only a matter of time before you do.

The good news is that of those thousands of circulating viruses, only a small

proportion have the means to do real damage to your data. In fact, the term

“computer virus” identifies a broad array of programs that have only one

feature in common: they “reproduce” themselves automatically by attaching

themselves to host software or disk sectors on your computer, usually without

your knowledge. Most viruses cause relatively trivial problems, ranging from

the merely annoying to the downright insignificant. Often, the primary

consequence of a virus infection is the cost you incur in time and effort to track

down the source of the infection and eradicate all of its traces.

Why worry?

So why worry about virus infections, if most attacks do little harm? The

problem is twofold. First, although relatively few viruses have destructive

effects, that fact says nothing about how widespread the malicious viruses are.

In many cases, viruses with the most debilitating effects are the hardest to

detect—the virus writer bent on causing harm will take extra steps to avoid

discovery. Second, even “benign” viruses can interfere with the normal

operation of your computer and can cause unpredictable behavior in other

software. Some viruses contain bugs, poorly written code, or other problems

severe enough to cause crashes when they run. Other times, legitimate

software has problems running when a virus has, intentionally or otherwise,

altered system parameters or other aspects of the computing environment.

Trackingdown thesource of resulting systemfreezes or crashescan drain time

and money from more productive activities.

Beyond these problems lies a problem of perception: once infected, your

computer can serve as a source of infection for other computers. If you

regularly exchange data with colleagues or customers, you could unwittingly

pass on a virus that could do more damage to your reputation or your dealings

with others than it does to your computer.

Preface

viii McAfee VirusScan

The threat from viruses and other malicious software is real, and it is growing

worse. Some estimates have placed the total worldwide cost in time and lost

productivity for merely detecting and cleaning virus infections at more than

$10 billion per year, a figure that doesn’t include the costs of data loss and

recovery in the wake of attacks that destroyed data.

Where do viruses come from?

As you or one of your colleagues recovers from a virus attack or hears about

new forms of malicious software appearing in commonly used programs,

you’ve probably asked yourself a number of questions about how we as

computer users got to this point. Where do viruses and other malicious

programs come from? Who writes them? Why do those who write them seek

to interrupt workflows, destroy data, or cost people the time and money

necessary to eradicate them? What can stop them?

Why did this happen to me?

It probablydoesn’t console you much to hear that the programmer who wrote

the virus that erased your hard disk’s file allocation table didn’t target you or

your computer specifically. Nor will it cheer you up to learn that the virus

problem will probably always be with us. But knowing a bit about the history

of computer viruses and how they work can help you better protect yourself

against them.

Virus prehistory

Historians have identified a number of programs that incorporated features

now associatedwith virus software.Canadian researcher and educator Robert

M. Slade traces virus lineage back to special-purpose utilities used to reclaim

unused file space and perform other useful tasks in the earliest networked

computers. Slade reports that computer scientists at a Xerox Corporation

research facility called programs like these “worms,” a term coined after the

scientists noticed “holes” in printouts from computer memory maps that

looked as though worms had eaten them. The term survives to this day to

describe programs that make copies of themselves, but without necessarily

using host software in the process.

A strong academic tradition of computer prank playing most likely

contributed to the shift away from utility programs and toward more

malicious uses of the programming techniques found in worm software.

Computer science students, often to test their programming abilities, would

construct rogue worm programs and unleash them to “fight” against each

other, competing to see whose program could “survive” while shutting down

rivals. Those same students also found uses for worm programs in practical

jokes they played on unsuspecting colleagues.

Preface

Some of these students soon discovered that they could use certain features of

the host computer’s operating system to give them unauthorized access to

computer resources. Others took advantage of users who had relatively little

computer knowledge to substitute their own programs—written fortheir own

purposes—in place of common or innocuous utilities. These unsophisticated

users would run what they thought was their usual software only to find their

files erased, to have their account passwords stolen, or to suffer other

unpleasant consequences. Such “Trojan horse” programs or “Trojans,” so

dubbed for their metaphorical resemblance to the ancient Greek gift to the city

of Troy, remain a significant, and growing, threat to computer users today.

Viruses and the PC revolution

What we now think of as true computer viruses first appeared, according to

Robert Slade, soon after the first personal computers reached the mass market

intheearly 1980s.Otherresearchers date theadvent of virus programs to1986,

with the appearance of the “Brain” virus. Whichever date has the better claim,

the link between the virus threat and the personal computer is not

coincidental.

The new mass distribution of computers meant that viruses could spread to

many more hosts than before, when a comparatively few, closely guarded

mainframe systems dominated the computing world from their bastions in

large corporations and universities. Nor did the individual users who bought

PCs have much use for the sophisticated security measures needed to protect

sensitive data in those environments. As further catalyst, virus writers found

it relatively easy to exploit some PC technologies to serve their own ends.

Boot-sector viruses

Early PCs, for example, “booted” or loaded their operating systems from

floppy disks. The authors of the Brain virus discovered that they could

substitute their own program for the executable code present on the boot

sector of every floppy disk formatted with Microsoft’s MS-DOS, whether or

not it included system files. Users thereby loaded the virus into memory every

time they started their computers with any formatted disk in their floppy

drives. Once in memory, a virus can copy itself to boot sectors on other floppy

or hard disks. Those who unintentionally loaded Brain from an infected

floppy found themselves reading an ersatz “advertisement” for a computer

consulting company in Pakistan.

With that advertisement, Brain pioneered another characteristic feature of

modern viruses: the payload. The payload is the prank or malicious behavior

that, if triggered, causes effects that range from annoying messages to data

destruction. It’s the virus characteristic that draws the most attention—many

virus authors now write their viruses specifically to deliver their payloads to

as many computers as possible.

Preface

x McAfee VirusScan

Fora time,sophisticated descendants of this first boot-sectorvirus represented

the most serious virus threat to computer users. Variants ofboot sector viruses

also infect the Master Boot Record (MBR), which stores the partition

information your computer needs to figure out where to find each of your

hard disk partitions and the boot sector itself.

Realistically, nearly every step in the boot process, from reading the MBR to

loading the operating system, is vulnerable to virus sabotage. Some of the

most tenacious and destructive viruses still include the ability to infect your

computer’s boot sector or MBR among their repertoire of tricks. Among other

advantages, loading at boot time can give a virus achance to do itswork before

your anti-virus software has a chance to run. Many McAfee VirusScan’s

anti-virus products anticipate this possibility by allowing you to create an

emergency disk you can use to boot your computer and remove infections.

But most boot sector and MBR viruses had a particular weakness: they spread

by means of floppy disks or other removable media, riding concealed in that

first track of disk space. As fewer users exchanged floppy disks and as

software distribution came to rely on other media, such as CD-ROMs and

direct downloading from the Internet, other virus types eclipsed the boot

sector threat. But it’s far from gone—many later-generation viruses routinely

incorporate functions that infect your hard disk boot sector or MBR, even if

they use other methods as their primary means of transmission.

Thosesameviruseshavealsobenefittedfromseveralgenerationsofevolution,

andthereforeincorporatemuchmoresophisticatedinfectionandconcealment

techniques that make it far from simple to detect them, even when they hide

in relatively predictable places.

File infector viruses

At about the same time as the authors of the Brain virus found vulnerabilities

in the DOS boot sector, other virus writers found out how to use other

software to help replicate their creations. Anearly example of this type of virus

showed up in computers at Lehigh University in Pennsylvania. The virus

infected part of the DOS command interpreter COMMAND.COM, which it

used to load itself into memory. Once there, it spread to other uninfected

COMMAND.COM files eachtime a userentered any standard DOScommand

that involved disk access. This limited its spread to floppy disks that

contained, usually, a full operating system.

Later viruses quickly overcame this limitation, sometimes with fairly clever

programming. Virus writers might, for instance, have their virus add its code

to the beginning of an executable file, so that when users start a program, the

virus code executes immediately, then transfers control back to the legitimate

software, which runs as though nothing unusual has happened. Once it

activates, the virus “hooks” or “traps” requeststhat legitimate software makes

to the operating system and substitutes its own responses.
