Many people have anti-virus software installed on their computers. They trust their anti-virus software and rely on these intelligent and powerful tools to protect their system security. However, how do you know about anti-virus software? Is anti-virus software always mighty in protecting your computer? See what you will get here.

Anti-virus Software, or Safe-defend Software, is a kind of program tool being able to get rid of all the program codes, such as virus and Trojans, etc., which are harmful to a computer.

In recent years, many terms such as Internet Security Suite, Overall Security Suite appear one after another, are also a kind of software used to clean computer viruses, Trojans and malicious software. Anti-virus Software usually integrates utilities including monitoring and identifying, virus scan and removal, as well as automatic update, etc., while some other anti-virus software also has utility on data restoring.

1. It is impossible for anti-virus software to remove all the viruses.

2. The anti-virus software is not always able to remove any virus it has found.

3. On a computer, for each operating system, there should not be two or more anti-virus software installed at the same time.(Exception is for anti-virus software that are compatible or produced by the same developer.)

4. At present, there are several ways that anti-virus software may use to deal with the infected file:

1. Clean up. The anti-virus software does not delete the infected file, but tries to clean up the virus codes from the infected file. Therefore, this way is also called Repair.

2. Remove. The anti-virus software removes the infected file detected completely.

3. Rename. The anti-virus software renames the infected file, so that the virus program won't be able to execute as it can't find a corresponding file.

4. Ignore. The anti-virus software can not clean up the infected file with different methods, or users choose not to deal with the file.)

To sum up, users should be clear that the anti-virus software is always lagging behind the computer viruses. Therefore, along with updating the version of anti-virus software at real time and scanning your computer regularly, users should learn more about the computer security and network security. And, do not open an unknown file or an unsafe website; do not visit the unhealthy website; remember to update your own private password if necessary, etc. Only in this way can your computer and network security be protected and guaranteed.
