2, for networked users, please break off the network before antivirus.

Non-system viruses that have been activated or are in attack

In this case, if the antivirus in the general Windows environment, the effect may be greatly compromised. Although, now anti-virus software can kill memory virus, but this technology is not mature after all, not necessarily can destroy the virus.

Therefore, the killing of such viruses should be done in Windows Safe mode. In Windows Safe mode, these viruses are not activated at startup, we can safely antivirus.

Third, the system files in the virus

This kind of virus is more difficult, so please back up before operation.

Killing this type of virus must be done in a clean DOS environment. Sometimes it has to be repeated to wipe out. (If antivirus success is estimated to have such a system problem under Windows).

Four, network virus

This type of virus must be broken in the case of the network can be removed, and after the removal is very easy to be infected! To eradicate this type of virus must rely on the efforts of network administrators!

V. Infection antivirus manufacturers to provide special anti-virus tool virus

Kill this kind of virus is good to do, just download the free dedicated anti-virus tool on the line. Special Antivirus tool antivirus accuracy is relatively high, so I recommend the use of Special anti-virus tool when conditions permit. Encounter what virus to search engine first search, do not rush to ask others, because first oneself master antivirus technique more convenient, the second reply most people also is on the Internet to find the method, they do not understand your specific situation, but caused a disservice.

VI. Inspection of the registration form

The registry has always been a parasitic place for many trojans and viruses to "favor", noting that the registry should be backed up before checking the registry.

1, check the registry HKEY_LOCAL_MACHINE Softwaremicrosoftwindowscurrent Versionrun and Hkey_local_machinesoftwaremicrosoft Windowscrentversionrunserveice, check the key values are not familiar with their own automatic startup files, extensions generally for EXE, and then remember the file name of the Trojan, and then search the entire registry, all see the same file name of the key value will be deleted, Then go to the computer to find the Trojan file hiding place to remove it completely. (Figure 3)

2, check the registry HKEY_LOCAL_MACHINE and Hkey_current_usersoftwaremicrosoft Internetexplorermain several items (such as localpage), if found that the key value has been modified, Just change it back according to your judgment. Malicious code, such as the "Million-valley", often modifies these items.

3, check the Hkey_classes_rootinifileshellopencommand and hkey _classes_roottxtfile ' shell Opencommand, and so on several common file types of the default open program is changed. This must be changed back, a lot of viruses are modified to scan. txt,. ini, and so on the default open program and can not be cleared.

Seven, antivirus antivirus six common misunderstanding

Myth 1: With anti-virus software I can not be afraid 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. "Faint? ￥%?# ..., really install anti-virus software more the better? In fact, the anti-virus software developed by different manufacturers can easily cause conflicts. 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, and therefore do not infect viruses. Just like Word, Excel and other data files because the executable code can be infected with the virus, and some viruses can let the hard disk files all formatted, therefore, we can not ignore the data file backup.
