How Antivirus Software Works
Most computer users know what antivirus software, but have no idea how it works. To know how it works is the key to choosing the right virus protection for your system.
The following is an overview of how antivirus software works.
Antivirus software is basically computer programs, software protect your system from malicious or harmful. The name "antivirus software" has its origin in the fact that it was originally developed to combat computer viruses. Now it has evolved into a sophisticated, all-encompassing anti-virus program.

The 2 methods of antivirus software, which protect your system
Antivirus software uses two different approaches to protect your system: (i) scanning of files, and (ii) in relation to suspicious behavior files from computer programs that can be infected.
Scanning: Scan can be explained by the prosecuting authority according to police statements. In principle, corresponds to a lowering (suspects) to a photo. To explain, when antivirus software scans the hard drive, for example, it is called a virus dictionary approach. It is so named because it looks for a match between a file on your hard drive and compares it with a "dictionary" of known viruses. If a piece of code in a file on your hard drive corresponds to the known virus in the dictionary, then swings the antivirus software into practice any of the following three measures: Repairing the file: The antivirus software will attempt to remove the infected file by Remove the virus, orIsolate File: The antivirus software will attempt to virus protection, by accessing the file offer programs. This keeps the virus spread, or
Delete the file: The antivirus software will delete the file, which unquestionably is the drastic form of virus protection.
The dictionary approach requires computer users download continuously updated versions of their antivirus software. This is because new entries (ie, viruses, malware, etc.) are constantly being added to the dictionary.

However, the user can continuously through their system and timing of the antivirus software to scan files to be monitored on a consistent basis scan. This may want daily, weekly, monthly, etc. In short, as often as she.
The suspicious behavior approach: The suspicious behavior, access to classified information about virus protection from the dictionary different approach. It monitors all programs on a system instead attempint to identify known viruses.
For example, if a program tries to keep a suspicious activity, such as writing data to an executable program, the antivirus software will alert the user, and ask them what actions they should take, if any.
One of the advantages of using the suspicious behavior is often cited approach to virus protection that it provides protection against new viruses. Remember approache with the dictionary, has the virus, first identified and listed.
To use a further analysis of the prosecution, which is like staking out a suspect because of his behavior. Even if it did not happen all the actions he takes It highlights the fact that it could be something.
