In the same case, it may be that there is a problem with your machine's DNS client service.
If it's different, it may be a Trojan horse.
It is recommended to check the virus as follows (none of the following takes into account the presence of viruses, so it is assumed that your computer is non-virus).
1. In the boot state, press win+r, enter cmd, enter ipconfig all in the command line window that appears, and find the place with "local connection" (if your operating system is Chinese) in the displayed content.
2. Find the line "IP address", see what the address behind is, if you are a cat connecting to the router and then connecting to the computer, this line should start with ", if the cat is directly connected to the computer, it should be the public IP address.
3. If the IP address shows "at the beginning, unfortunately there must be no connection to the network, you can try to restart the cat first, and then follow the steps to see if the IP address has changed, if not, call customer service**.
4. Continue to step 2, if the IP address is okay, just look at the following line of "DNS server", if the computer is connected to the router, it should be ", if the computer is directly connected to the cat, DNS should also be the public IP address, if it is empty, the same as step 3, restart the cat, if not, call customer service.
5. If the above is all right, still in the command line window, enter "ping, if the network is unblocked, it should show four.
The line is as follows: "reply from : bytes=* time=* ttl=*", otherwise the network is not connected, it is still a restart of the cat, and it is not possible to call customer service (the place mentioned in the above steps to restart the cat, if there is a router, also restart).
6. If the ping in step 5 is normal, or you can't open the web page and QQ can open, you can fix IE, or change the browser, you can play a lot of IE repair tools, it is recommended to use 360's IE repair function.
