Some friends may think that anti-virus is a simple task. Isn't it just by clicking the "anti-virus" button of anti-virus software? Anti-virus really requires anti-virus software, but it also requires skill!

This article does not introduce anti-virus software settings. This article mainly introduces the anti-virus environment.

In fact, the best anti-virus environment is the DOS started with a clean boot disk. However, it is unscientific to kill all viruses under DOS! It is a waste of time and reduces the service life of the DOS anti-virus disk. So how can we determine the environment in which the virus is to be killed?

1. Viruses in inactive non-system files

It's easy to kill this virus. You only need to kill it in a normal Windows environment. Generally, it can be wiped out.

2. Viruses in non-system files that have been activated or attacked

If the virus is detected in a Windows environment, the effect may be compromised. Although the current anti-virus software can detect and kill memory viruses, this technology is not yet mature and may not completely eliminate the virus. Therefore, the virus should be killed in Windows security mode. In Windows security mode, these viruses are not activated at startup. Therefore, we can safely eliminate viruses.

3. Virus in system files

This type of virus is difficult, so please back up before the operation. To kill such viruses, you must run them in a clean DOS environment. Sometimes it is necessary to scan and kill repeatedly before they can be completely cleared.

4. Network viruses (especially viruses transmitted through LAN)

This type of virus can be cleared only when the network is disconnected, and it is easy to be infected again after being cleared! It is up to the network administrator to eradicate the virus!

5. Virus Infection manufacturers provide specialized antivirus tools

To kill such viruses, you only need to download the free dedicated antivirus tool. The specific anti-virus tool has a relatively high precision. Therefore, we recommend that you use the specific anti-virus tool with conditional permission.

Anti-Virus is very skillful. However, anti-virus alone is not enough. We should also pay attention to anti-virus! In order to ensure real security, we must reject the virus from home. Therefore, it is important to select anti-virus software suitable for you and enable real-time monitoring at any time. Do not forget to upgrade the software.
