Why is my computer so slow when I get online?

If you install anti-virus software, it will make your computer run very slowly, but there is no way to install it, it is okay if you use 1m alone, if there are more people, others will go under the next thing, look at **, of course it will be very slow, or you click on the start menu, click Run, and then enter msconfig inside, and then click on the startup item, in addition to the antivirus software and ctfmon (font) you have installed, the other checks are removed, see if you can, if you still can't, You just go to kill the poison, or it may be a heavy malware, you go to get a super rabbit magic setting to clean up the system, or you go to get a malware cleanup assistant to clean up the malware!!

Hello. In your case, please analyze and solve it from the following aspects:

1 To keep your computer normal and free of viruses and malware, it is recommended to regularly use 360 Guard, Kingsoft Guard and other tools to clean up system junk and temporary files (IE cache) generated by the Internet, and check and kill malware. Restart your computer when you're done.

2. If the computer configuration is poor, try to set the virtual memory to a larger one, and the anti-virus software installation occupies a small amount of resources, such as nod32, or only install an auxiliary anti-virus software.

3 The cat has been left open for a long time, it is very hot and hot, it is recommended to place the cat in a ventilated place as much as possible, and do not overlap with the router. So as not to be too high, otherwise there will be a fake crash, restart the cat is better, it is really not good It is recommended to change a cat with good performance (I hit ** to telecom, free to change).

4 Several computers share the network, because the router is too poor, others use P2P to watch movies, etc., it will drag the router to death, restart the router will be better, the long-term solution is to change to a better enterprise-level router.

5 Microsoft's system actually reserves 20% of the network bandwidth to the system, we can take this part and use it, open Start - Run, enter :, open Group Policy, select Local Computer Policy - Computer Configuration - Management Template - Network - QoS Datagram Scheduler, double-click Limit on the right side to reserve bandwidth, set to disabled.

6. Modify the IP address to static settings to avoid slow startup of the computer, and after the IP lease expires, the IP will not be configured and the network will be disconnected.

7 Someone may have installed and used rate-limiting software on the network, it is recommended that you turn on the ARP firewall (360 has ARP protection).

8 It is recommended to manage the boot startup items and stop the useless startup items, especially those who look at the software of ** and **, which run in the background and account for the network speed. Start-Run-Enter msconfig-OK-Click "Start" in the "System Configuration Utility" window-Start, except for the input method (ctfmon) and anti-virus software, the general program can be turned off. You can also use 360 and other software to intelligently optimize boot acceleration.

9 It is recommended to install only one main antivirus software, as installing multiple will occupy computer resources, which will make the computer slower and the Internet will feel slower.

Hope it helps!!
