How does the antivirus software?

can any1 tell me or suggest a good website, thanks

From first viruses were created as experiments in the eighties, with the latest malicious code, a major concern for all computer users is the threat of the virus into their systems. To prevent the virus entering the system there are basically two options. The first is to place the computer in a protective bubble. In practice, this means isolating the machine, disconnect not through Internet or other network, using floppy disks, CD-ROM or other removable disk. Thus you can be sure that any virus will get into the team. You can also rest assured that no information will enter the computer, unless you write on the keyboard. So you can have an exceptional team, the perfect machine data processing ... but process data. If you're happy with that, the team approaches the largest Using a microwave oven. The second option is to install an antivirus program. These are designed to give you peace of mind that no malicious code can enter your PC. But how? How does the program allow you to install a game, but keep the virus from copying itself to disk? Well, that how it works .... An antivirus program is only a system of data analysis, and then, if you think something is infected, disinfect. The information is analyzed (or scanned) in different ways depending on where it comes. A virus works differently when the disk control operations when the monitoring of email traffic or movements in a LAN. The director is the same, but there are subtle differences. The information is in "system Origin "and must reach the" target system ". The source system could be a floppy disk and the target system might be the hard disk of a computer or the origin of an ISP that stores a message and the destination, the communication system Windows on the client machine, Winsock. The interpretation of the information system varies depending on whether it applies to operating systems, applications, or if special arrangements are needed. The mechanism of interpretation must be specific to each of which system or component in which the virus is to be applied. For example, in Windows 9x, a VxD virtual driver is used, which continuously monitors disk activity. This Thus, whenever the information on a hard disk or floppy disk is accessed, the antivirus will intercept calls to read and write to disk, and scan information to be read or saved. This is done through a kernel-mode driver in Windows NT/2000/XP or an NLM that intercepts disk activity on Novell. Antivirus products they are not specially designed for operating systems, but its application in other applications, have a different interpretation mechanism. For example, a CVP Firewalls antivirus, firewall is offered by the antivirus with information to explore through the CVP and antivirus SendMail, the MilterAPI information filter facilitates interpretation. Sometimes, a mechanism of interpretation is not provided by the virus (eg, a VxD) or application (Like CVP). In this case, special arrangements between the application and antivirus software should be used. In other words, resources and information interception go to antivirus, offering complete integration to disinfect the virus. Once the information has been explored, using any method, whether a threat has been detected, two operations are performed: 1. The clean data is returned to the mechanism of interpretation, which in turn return it to the system so it can continue towards its final destination. This means that if an email is being received, the message is allowed to pass the mailbox, or if a file is being copied, the copy process will be allowed to finish. 2. A notice is sent to the user interface. This user interface can vary greatly. In an antivirus for workstations, a message can be displayed on the screen, but server solutions for the alert can be sent as an e-mail, internal network message, an entry in an activity report or as some sort of message to the antivirus management tool. As you can see, antivirus programs do not perform miracles, nor is a software tool you need be careful. It is a very simple security ally that offers precision and advanced technology. Consider this: when you copy a few megabytes on the hard drive of your computer, antivirus should find more than 65,000 virus without affecting the normal operation of the computer without user's knowledge. antivirus programs offer a high level of protection and prevent any unpleasant surprises. It's as simple as putting $ XXX in a box for peace of mind. I am sure that we do not have serious doubts ... Scan Engines Regardless of how information is obtained to analyze the most important
