clean a system infected by a master boot record virus

If you have a hard drive that may have a boot virus on it, how do you clean the virus from the drive?

The "Master Boot Record" or MBR is loosely used to describe the combination of the "Partition Table" and the "Boot Record". The primary Partition Table is used as a pointer to additional partition tables that might exist on the drive. This set of partition tables forms a chain each maintaining pointers to the next partition table with a total of up to four partition tables on a drive. The primary partition table also has a pointer to the Boot Record. The Boot Record is a sector that contains information about the physical characteristics of the hard drive i.e. cylinders, heads, sectors,
drive ID, file system, and so on.

Viruses typically move the real MBR onto "slack space" sectors which is unused by your computer. Then it replaces the real MBR with it own version of the MBR where the real MBR belongs. This way the virus can manipulate the Boot…

how trojans work and how to stop a trojan horse

What is a Trojan?

A Trojan Horse is an unauthorized instruction contained within a program that performs functions unknown to (and probably unwanted by) the user. On a personal computer, trojans can be destructive to the system.

Why the name 'Trojan Horse'?

In the 12th century B.C., Greece declared war on the city of Troy. The dispute erupted when the prince of Troy abducted the queen of Sparta and declared that he wanted to make her his wife, which made the Greeks and especially the queen of Sparta quite furious. The Greeks gave chase and engaged Troy in a 10-year war, but unfortunately for them, all of their efforts went down the drain. Troy was simply too well fortified. In a last effort, the Greek army pretended to be retreating, leaving behind a huge wooden horse. The people of Troy saw the horse, and, thinking it was some kind of a present from the Greeks, pulled the horse into their city, without knowing that the finest soldiers of Greece were sitting inside it, since th…

simple living can yield millions in savings

Many people who lead simple-living lifestyles are millionaires. Their wealth is the result of hard work, perseverance, planning and self-discipline.
By Janet Luhrs

Many people already lead simple-living lifestyles and don’t know it. And many of them are millionaires. Proof can be found in the best-selling book, “The Millionaire Next Door,” by Thomas Stanley and William Danko. You’d never guess that the subject of millionaires could have anything to do with simple living, but it does.

Compulsive Savers versus the Rest of Us

The millionaires in this book were not born wealthy, nor do most of them have high-level, exotic jobs. What they do have are simple lifestyles! It’s the simple lifestyles, not the big paychecks that turned these people into millionaires. According to the book, their wealth is the result of hard work, perseverance, planning and most of all, self- discipline.

So why aren’t all of us hard-working souls rich?
Answer: We regularly and continually give our money away to oth…

set your world in motion

Being a creative professional means making the content you communicate clear, concise, and compelling. You’ve got a lot of techniques at your disposal: color, typography, photography, illustration, and so on. But no technique is more powerful than motion. In reality, the world does not stand still. If you are a graphic or web designer, an art director, commercial artist, photographer, illustrator, a communicator at work, or a fine artist, you see video and motion graphics overlapping in many different ways.

A basic understanding of digital video can help you expand your creative reach. When you show a sequence of still images to a human eye, the brain
 fills in the gaps and perceives continuous motion. Film and video use this same principle to animate photographic images, which appear to fluidly move when shown sequentially at
 an appropriate rate. With similar functions, the difference between film and video is a
 matter of physical media as well as genre. Some audiences believe tha…
