How does Norton AntiVirus prevent infections?
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. Some, however, are programmed specifically to damage data by corrupting programs, deleting files, or reformatting disks. Symantec engineers track reported outbreaks of computer viruses to identify new viruses. Once a virus is identified, information about the virus (a virus signature) is stored in a virus definitions file, which contains the necessary information to detect and eliminate the virus. When Norton AntiVirus scans for viruses, it is searching for these telltale virus signatures.

The Norton AntiVirus LiveUpdate feature makes sure your virus protection remains current. Updated virus definitions files are available from Symantec regularly. With LiveUpdate, Norton AntiVirus connects automatically to a special Symantec site, determines if your files need updating, downloads the proper files, and installs them in the proper location. Virus infections can be easily avoided. Viruses that are quickly detected and removed from your computer cannot spread to other files and cause damage. Norton AntiVirus uses a variety of methods to detect file, boot, and macro viruses early: File System Realtime Protection: Constantly monitors activity on your I computer by looking for virus signatures when a file is executed or opened, and when modifications have been made to a file, such as renaming, saving, moving, or copying a file to and from folders.

To supplement detection of known viruses, Norton AntiVirus includes a powerful component called Bloodhound. With this advanced heuristic technology, Norton AntiVirus can detect a high percentage of new or unknown viruses not yet analyzed by antivirus researchers. Signature-based scanning: Norton AntiVirus relies on signature or I pattern-based scanning to detect viruses. Norton AntiVirus searches for residual virus signatures in infected files. This search is called a scan. If a virus signature is detected, Norton AntiVirus notifies you that one or more of your files is infected.

The strength behind the Norton AntiVirus Corporate Edition protection lies in the Symantec AntiVirus Research Center (SARC). The increasing number of computer viruses, currently over 40,000 are known, requires effort to track, identify, and analyze new viruses and virus technologies. SARC researchers disassemble each virus sample to discover its identifying features and behavior. With this information, they develop a virus definition that Symantec products use to detect and eliminate the new virus…
