Six mistaken ideas of computer antivirus antivirus

Our computer will be subject to the virus at any time, antivirus anti-virus is one of the things that our computer users need to do. However, in many cases, our understanding of antivirus antivirus is there is a mistake, misunderstanding.

Small knitting here to organize several of our misunderstanding.

　　Common anti-virus antivirus six major misunderstanding:

　　Myth 1: With anti-virus software I can be no fear of any poison.

Really have anti-virus software is not afraid of what poison? The answer must be no.

The virus is constantly having new occurrences, and its appearance is often unpredictable, anti-virus software to constantly new, constantly upgrade to deal with the emergence of viruses, even so, there are many times anti-virus software upgrades to the latest can not kill all the virus, upgrade to the latest, just can let your computer refused more virus, Make your computer in a more secure state, does not mean that you can ignore computer security, usually pay attention to sharing security; Do not download unknown programs, do not open the unknown page and so on.

　　Myth 2: Install anti-virus software more the better

Two days ago, the author to help a friend installed, friends do not understand the computer, so I said: A few anti-virus software, I am afraid of the internet a lot of poison. Do you really want to install anti-virus software more and better?

In fact, the anti-virus software developed by different manufacturers can easily cause conflict. Many antivirus manufacturers in order to avoid this situation, in the installation of the test computer is installed with other anti-virus software, the purpose is to avoid two anti-virus software at the same time when the conflict occurred. Moreover, for most of the virus, a general anti-virus software can be killed, to deal with special viruses also have a lot of dedicated kill tools. The more anti-virus software installed, in addition to the possibility of conflict, but also consumes more system resources, slowing down the speed of computer operation. More than a few anti-virus software, benefit nothing, the possibility of loss of efficiency is very large. So, not the more anti-virus software the better.

　　Myth 3: Antivirus software can be the right to antivirus

Antivirus software can antivirus on the line? Is it not until the virus invasion and then to antivirus? Some people installed anti-virus software, want to reduce the consumption of the system resources, anti-virus software will be turned off, when the virus intrusion when the anti-virus software is not antivirus. This consciousness is not good, now the virus is popular, can be all-pervasive, accidentally, you are very easy to "poisoned", and now the big hard disk, so many anti-virus software antivirus time is very long, and if the virus invasion, then anti-virus, then may be your system has already collapsed, the data has already been lost, too late, then the loss will be big. Therefore, antivirus is not the focus, prevention is the most important. Anti-Virus software is not so much better than antivirus software!

　　Myth 4: As long as I do not surf the internet, there will be no virus

Some people's computers connect to the Internet, thinking that as long as the Internet does not open the web will not infect the virus, so do not open anti-virus software antivirus. In fact, although many viruses are spread through the web, but there are a lot of viruses do not wait for you to open the Web page has already invaded your machine, this is necessary to prevent. Shock waves, worms, and so on, will get you into the computer unconsciously. Moreover, pirated CDs, U disk will also exist virus. Therefore, as long as your computer is on, it is best to prevent!

　　Myth 5: File Set straight read-only to avoid viruses

Set read-only, only several commands are invoked and the virus can invoke system commands. Therefore, the virus can get rid of file properties, serious can delete important files, format the hard disk, let the system crash! Set straight read-only, and can not be effective anti-virus, but for the local area network in order to share security, to prevent accidental deletion, set straight read-only property is more useful.

　　Myth 6: Virus does not infect data files

Some people think that the virus is a program, and data files such as *.txt,. *pcx and other format files generally do not contain programs, so will not infect the virus. Just like Word, Excel and other data files because the executable code can be infected, and some viruses can let the hard disk files all formatted, so we can not ignore the data file backup.

Hope that we can correct their understanding of the mistakes, to avoid computer poisoning caused by the huge loss of the occurrence!
