Please analyze and solve your situation from the following aspects:

1 If you want to keep your computer normal and free from viruses and malicious software, it is recommended to use tools such as 360 Guardian and Kingsoft Guardian to regularly kill malicious software on cclean and temporary files (i.e. cache) generated on the Internet. Restart the computer when it is finished.

2 The computer configuration is poor. Try to set the virtual memory as large as possible, install antivirus software with small resources, such as nod32, or just install an auxiliary antivirus software.

The cat has been driving for a long time and is very hot. It is recommended to put the cat in a ventilated place as far as possible and not overlap with the router. In case the temperature is too high, or there will be a fake crash, it will be better to restart the cat. I really can't suggest changing a cat with good personality (I called Telecom to change it for free).

4 Several computers * * * use the Internet. Because the router is too bad, others will use p2p to watch movies and so on. , will drag the router to death. It would be better to restart the router. The long-term solution is to suggest a better enterprise router, and then set and allocate the network speed.

Microsoft's system actually reserves 20% of the network bandwidth for the system. We can use this part, open Start-Run in turn, enter gpedit.msc, open Group Policy, select Local Computer Policy-Computer Configuration-Management Template-Network -qos Datagram Scheduler, double-click on the right to limit the reserved bandwidth and set it as disabled.

6. Change the ip to a static setting to prevent the computer from starting slowly. After the ip lease expires, the ip cannot be configured and the network is disconnected.

Some people may install and use speed-limiting software in the network. I suggest you open the arp firewall (360 is protected by arp).

It is suggested to manage startup items and stop useless startup items, especially watching videos and downloading software, because background operation occupies the network speed. Start-Run-Enter msconfig—- OK-Click Start-Start in the system configuration utility window. Except Ctfmon and antivirus software, all general programs can be closed. You can also use software such as 360 to intelligently optimize boot acceleration. (cqjiangyong summary: Many computers are slow because the background p2p software is running, which accounts for the network speed)

It is recommended to install only one main antivirus software. Installing more than one will take up computer resources, slow down the computer and make the Internet feel very slow.
