Precautions for using security software

I. A large number of resources

Some people feel like installing a few more anti-virus software sets and firewalls. The opposite is true! Because different software companies use different anti-virus engines and methods for virus identification, there is a big difference between different anti-virus software. Therefore, there are serious compatibility problems that make them unable to work normally. In addition, anti-virus software is competing with the same virus in order to take the initiative to intercept the virus in memory in advance, too many anti-virus software installed will only seriously consume resources. As a result, security is not guaranteed, and the system performance is greatly discounted.

Correct practice: a set of anti-virus software with real-time monitoring and a suitable network firewall

2. Virus and network firewalls are indispensable

Everyone can understand how to install anti-virus software, but what is the use of the network firewall? To put it simply, the former Prevents viruses from entering your system, and the latter disconnects the virus from the outside, which is especially effective for Trojans.

Careful friends will find that just install the winsp-sp2 system or install network firewall after the Internet to Open QQ or BT or even the browser will prompt "XX program attempts to connect to the network, is allowed ?" To prevent Trojans and other malicious programs from accessing the network. Therefore, once a trojan is infected, the network firewall will not be afraid of the leakage of personal data.

At the same time, the network firewall also prevents attempts to access your system and cut off malicious attacks from the source. The simplest example is that you are familiar with the network command "ping". Many people with ulterior motives First Use this command to probe your network defense status and obtain your IP address, and then expand the network attack. However, if you use the network firewall, you can only ping it. At the same time, the network firewall also comprehensively monitors the dynamics of each port of the system to ensure the security of the local and network connections.

Some professional friends who want to study the network and want more information feedback and functions can use the "Rising Star Personal Firewall ".

Iii. Summary

Finally, I suggest you always look at the process as a caring person? Are there any inexplicable problems with hard disk read/write and software running? When surfing the Internet, check the network status.

I believe that you will find that the virus is not as terrible as you think, and it is not as difficult as anti-virus!
