All of a sudden, the internet speed became very slow

My machine too,It's going to slow down after a while.,Not only the network speed.,The system will also be slow.,360+ Kaba is a little better to use together.,But there's a problem.,How to kill the virus is not as good as restoring the system.,I always feel that it's slower than just installing the system.,If you don't have a system backup,,It is recommended that you reinstall the system.,Make a backup after installing the software you need.,And then install the software that can be used without installing QQ to other disks.,There's a big problem to restore it later.。

If everything worked fine before, there are several possibilities:

1. My machine is poisoned.

2. I am not poisoned, but other machines that share the Internet with me are poisoned and occupy a lot of network bandwidth.

3. The egress route is slowed down due to some external attack.

4. Using ACL limits your access speed on egress routes.

5. A P2P program is running on the intranet or the local machine, which occupies a lot of bandwidth.

Is your antivirus software being updated, or you have too much software open and the memory is insufficient?

Use 360 to kill bad review software and Trojan horses, and then use Super Bunny or Windows Cleanup Assistant to clean up system junk.

Is it poisoned. I've done it before, and I've recovered after I killed the virus.

It may be that the BT software is taking up too much; Data or memory.

To restore, there is too much junk in the system.

Reasons for slow internet speed.

1.Viruses and Trojans can cause slow network speeds.

3.Multiple computers share the Internet, and the computers in the shared network may have ARP virus, and the solution is to find the source of the attack, so that the scum can use Kingsoft Guard to kill the computer.

4.Another is the broadband environment you are in, it is possible that the broadband line is aging, and the router is broken, resulting in slow network speed.

5.Your computer and ** are in a different network environment, such as the access between Netcom users and telecommunications**, and the network speed will also slow down.

6.There is also a problem of **itself, the quality of the server is very poor, and the network speed is slow due to limited bandwidth.

A solution to a slow internet connection.

First of all, it is ruled out that the network speed is slowed down due to external factors, such as its own problems, aging or damaged equipment in broadband environments. If external factors are excluded, then internal factors are addressed.

First, Kingsoft Guardian can easily help you repair the incurable disease of IE components being damaged caused by virus Trojans.

1. Enter the main interface and enter [Trojan].

2. Then click [Quick Scan].

Second, first check whether your computer is attacked by ARP virus, such as the suspect first**Kingsoft Shell ARP firewall, if there is an ARP virus attack on the LAN, Kingsoft Shell ARP Firewall will alarm, prompting the attack from which IP computer is issued, and then contact the network management to use Kingsoft Guardian to kill the attacking computer.

Three,.If there is no virus problem, then check if there is a programmer that is taking up a lot of bandwidth and slowing down the Internet speed.

How it works: 1. Open Kingsoft Guardian and enter the "System Optimization" tab.

2. Turn on the "Traffic Monitoring" function, find the program that occupies a large amount of traffic and end it. "

Follow my method to solve the problem, and ask me if it doesn't work.
