Book Description
PC viruses are not necessarily a major disaster despite what is sometimes written about them. But a virus infection is at the very least a nuisance, and potentially can lead to loss of data. Quite often it is the user's panic reaction to discovering a virus infection that does more than the virus itself. This book demystifies PC viruses, providing clear, accurate information about this relatively new PC problem. It enables managers and PC users to formulate an appropriate response; adequate for prevention and cure, but not `over the top'. Over 100 PC viruses and variants are documented in detail. You are told how to recognise each one, what it does, how it copies itself, and how to get rid of it. Other useful and relevant technical information is also provided. Strategies for dealing with potential and actual virus outbreaks are described for business, academic and other environments, with the emphasis on sensible but not unreasonable precautions. All users of IBM PC or compatible computers - from single machines to major LAN's - will find this book invaluable. All that is required is a working knowledge of DOS. Dr. Alan Solomon has been conducting primary research into PC viruses since they first appeared, and has developed the best-selling virus protection software Dr. Solomon's Anti-Virus Toolkit.

Book Description
Aujourd'hui il est inutile de payer pour disposer d'une bonne protection contre les virus. Mais un antivirus seul est une protection illusoire car les logiciels espions (spyware) et les hackers passent tres facilement la protection d'un pare-feu (firewall)et d'un antivirus. Dans le cadre de mon association, j'aide les internautes a verifier que leur ordinateur n'a pas ete hacke a leur insu et je vous aiderai a vous proteger contre toutes ces menaces.

Book Description
The 1980's saw the advent of widespread (and potentially damaging) computer virus infection of both personal computer and mainframe systems. The computer security field has been comparatively slow to react to this emerging situation. It is only over the last two years that a significant body of knowledge on the operation, likely evolution and prevention of computer viruses has developed. A Pathology of Computer Viruses gives a detailed overview of the history of the computer virus and an in-depth technical review of the principles of computer virus and worm operation under DOS, Mac, UNIX and DEC operating systems. David Ferbrache considers the possible extension of the threat to the mainframe systems environment and suggests how the threat can be effectively combatted using an antiviral management plan. The author addresses the latest developments in "stealth" virus operations, specifically the trend for virus authors to adopt extensive camouflage and concealment techniques, which allow viruses to evade both existing anti-viral software and to avoid detection by direct observation of machine behaviour. A Pathology of Computer Viruses addresses a distinct need - that of the computer specialist and professional who needs a source reference work detailing all aspects of the computer virus threat.

Book Description
This Book Is One Of The Most Valuable Resources In The World When It Comes To The Damaging Facts About Computer Viruses! Is the fact that you would like to protect your digital devices but just don’t know how making your life difficult.. maybe even miserable? Does it seem like you’ve tried everything in your power to figure it out, and yet, despite your best intentions, you’re still plagued with: • Not knowing how to even get started • Not understanding even where to start with malware • Not knowing how to identify the right ant-virus program If this describes you, then you are in luck today... First, you are NOT alone! It may seem like it sometimes, but not knowing how to protect your PC is far more common than you’d think. I ought to know, because I’ve been in the same spot before... “Why Understanding All The Ins And Outs Of Avoiding Viruses Is Crucial!” First, you are NOT alone! It may seem like it sometimes, but not knowing how to get started with being less stressed is far more common than you’d think. I ought to know, because I’ve been in the same spot before... You Need to Understand Stress to Beat it This is one area you must pay attention to... A virus will function as an element that will constitute damage to the hard disk contents or interfere with the normal operational executions of the computer system. This will cause the computer to be unable to function properly until the virus is eliminated and the overall system is overhauled and rebooted. Let me explain... A virus program is usually able to replicate itself and this too is an added problem once the virus latches on to a system. Progressively getting out of control, the virus will attempt to cause as much damage as possible before it can be detected and eliminated. The replication is usually intentional and designed to act just like a Trojan, thus causing the unsuspecting user being caught off guard. If a file that contains a virus is opened, or copied onto another computer, then the other computer will also become infected and this process is repeated every time the file is opened and downloaded onto other systems. And the worst part? The more you don’t know the less you will succeed! Make no mistake about it... “The Costs of NOT Getting All The Info You Need Are Just Too High!” Your lack of knowledge in this area may not be your fault, but that doesn’t mean that you shouldn’t — or can’t — do anything to find out everything you need to know to finally be a success! The costs of continuing to repeat this pattern are just too steep... I mean, think about all of the money you’re wasting because of how continuing to try things that don’t work costs you money... the time you’re losing due to going around in circles is also time-consuming... ... and that’s not to mention the toll it’s taking on your personal life, like the way the failed attempts over and over can impact even your business. So today — in the next FEW MINUTES, in fact — we’re going to help you GET ON TRACK, and learn how you can quickly and easily get your PC issues under control... for GOOD! “This Book Below Will Show You Exactly What What You Need To Do To Finally Be A Success With Your Protecting Your PC!” In This Amazing eBook You Will Learn * What Is A Computer Virus? * How Are Viruses Spread? * How Bad Can A Virus Attack Be? * What Is A Malware? * Getting The Right Anti-Virus For Pc And much, much more...

Book Description
For those who didn't buy the first edition, welcome aboard. For those who did buy the first edition, welcome back, and thanks for making the second edition possible. For those who bought the first edition and are standing in the book store wondering whether to buy the second, what's in it for you? Well, for one thing, it's smaller. (No, no! Don't leave!) I tried to make the first edition a kind of master reference for antiviral protection. That meant I included a lot of stuff that I thought might possibly be helpful, even if I had some doubts about it. This time I've tried to be a little more selective. I've added a little more material to Chapter 4 (Computer Opera tions and Viral Operations) dealing with the question of computer vi ruses infecting data files and the new "macro" viruses. I've added two new sections to Chapter 7 (The Virus and Society). One looks at the increasing problem of false alarms while the other looks at the ethics of virus writing and exchange.
