Tips for anti-virus and re-Infection

In many cases, the same computer often has the same virus repeatedly. For example, it's okay for me to get rid of the virus just after being infected with the bad postmaster. However, after a while, the virus is not recommended. This is the so-called "re-infection of the same virus ". In fact, there are some tips on how to prevent another virus infection.

There are two common causes for re-virus infection: first, the virus has a new variant, and second, it has not blocked the transmission path of the virus. For the first reason, we can completely solve the problem after we upgrade anti-virus software online to the latest version. The second reason is that the following situations are often caused by the use of computers. We can solve the problem of re-infection of viruses by taking them seriously and treating them differently.

1. System and tool software vulnerabilities

Many viruses spread by exploiting vulnerabilities in operating systems and network tools, such as cover letters, bad spenders, and monsters. They exploit the "Iframe" vulnerability of Microsoft browser software, even if the user does not open the email attachment and only clicks the email, the virus runs automatically.

2. Virus camouflage, to lure users

This is a common method for most worms and Trojans. The title or content of a letter can entice users to open the text of attachments, and use chat tools to spread websites containing malicious code.

3. Insufficient user security awareness

Some users are easy to use, and management of passwords is too simple and relaxed. For example, save the password to your computer and use a regular and simple password, such as 1234, abcd, or even empty password, in this way, some viruses with password guessing functions will be created to spread.

4. lax lan Management

All computers in the LAN can be interconnected and shared resources can be used very freely. No corresponding permissions are set for the use of shared resources.

5. No common Antivirus

A small number of users among friends, family members, and contacts are also infected with viruses.

All of the above factors will cause re-infection of viruses. In actual use, we often simply conduct anti-virus after poisoning, without blocking the channel of virus intrusion, this will cause frequent virus harassment and complain that anti-virus software is not used, seriously affecting normal operations.

Today's viruses are "all-in-one", some of which are malignant viruses, such as "monsters", which can be used together to spread the virus, greatly enhancing the efficiency of virus infection. In order to prevent such viruses from being infected, it is not only necessary for antivirus software vendors to work efficiently, but also for Internet users to improve their awareness of defense. In the same way, only some people are doing anti-virus, or only prevent a certain channel of virus transmission, and the real purpose of comprehensive anti-virus is not achieved. Therefore, only when the majority of users have improved their awareness of anti-virus security and blocked all the ways of virus infection can they truly make the virus accessible without holes.
