Welcome to NortonAntiVirus …….

A virus is simply a computer program designed in such a way that, when run, it attaches a copy of itself to another computer program or document. Thereafter, whenever the infected program is run or a document containing a macro virus is opened, the attached virus program is activated and attaches itself to yet other programs and documents. In addition to replicating, viruses are generally programmed to deliver a payload. Most viruses simply display a message on a particular trigger date.

While the Internet gives you access to a large quantity of information and business opportunity, it also exposes your computer to a multitude of security threats that most of us are not aware of.

Virus: A computer virus attaches itself to a program or file so it can spread from one computerto another, leaving infections as it travels. Much like human viruses, computer virusescan range in severity: Some viruses cause only mildly annoying effects while otherscan damage your hardware, software or files. Almost all viruses are attached to anexecutable file, which means the virus may exist on your computer but it cannot infectyour computer unless you run or open the malicious program. It is important to notethat a virus cannot be spread without a human action, (such as running an infectedprogram) to keep it going.

Virus definition: Virus definitions (or signatures) contain a unique sequence of bytes used by an anti-virus program to identify each piece of malicious code. Signature analysis is one of the key methods used to find and remove malicious code.

Worms: Worms are generally considered to be a subset of viruses, but with key differences. A worm is a computer program that replicates, but does not infect other files: instead, it installs itself on a victim computer and then looks for a way to spread to other computers.

A Canon digital camera (or digicam) is a camera that takes videos or still photographs, or both,simply by recording images via an electronic image sensor. It is the main device used in the field of digital photography. Most 21st century cameras are digital.

Canon Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, and deleting images to free storage space. The majority, including most compact cameras, can record moving videoes with sound as well as still photographs. Some can crop and stich pictures and perform other elementary image editing. Some have a GPS receiver built in, and can produce Geotagged photographs.
The optical system works the same as in flim cameras, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, just as with film but the image pickup device is electronic rather than chemical. Most digicams, apart from camera phones and a few specialized types, have a standard tripod screw .
Digital cameras are incorporated into many devices ranging from PDFs and any mobile phone http://astore.amazon.com/mywoinmyha-20 (called camera phones) to vehicles.
