Computer can login QQ, but can not browse the Web, solution summary

"Note": For reference only, personal experience

This morning, the computer suddenly can only log on QQ, can not surf the internet, never encountered this problem I began various Baidu methods, all kinds of attempts, and finally successfully solved the problem

1. First can login QQ, can not browse the Web page, the reason is suspected of DNS;

2. Open cmd, test, you can ping Baidu's IP address, but ping different domain names;

3. Classmate's computer uses the same DNS and gateway, but can surf the Internet;

4. Make sure that DNS is the bane of the mess.

but a search on the internet has the following possibilities:

1. Ip/dns was maliciously tampered with.

2. DNS is hijacked

3. caused by a virus.

4. Related to setting up a proxy server

5. Browser corruption

6. Problems with DNS

Next, I started a step-by-step troubleshooting ...

Solutions for the above six scenarios:

The first type:

1. Change adapter settings, network and internet-> Network and Sharing Center, Control panel

2. Right click on the wireless network connection, click Properties, click on Internet Protocol version 4 (TCP/IPV4), click Properties, check the IP address and DNS is automatically obtained, if, then exclude the first error, if not, click on automatic Access;

3. Try browsing the web (I failed).

The second type:

1. Try browsing the web (I failed again).

The third type:

1. In the task Manager to see the process, (into the method, put the mouse on the taskbar, right-Task Manager-process) to see how the CPU occupancy rate, if it is 100%, can be sure, is infected with the virus, then you want to run other programs simply suffer. This is to find out which process is greedy to occupy the CPU resources;

2. After finding the record name, then click Finish, if not end, then to boot into safe mode to delete the Dongdong, but also to enter the registration table, (method: Start-run, input regedit) in the Registry dialog box, click Edit-Find, enter the program name, found, click the right mouse button delete, Then a few more searches, often can be completely removed clean;

3. Try browsing the web (I failed again).

The fourth type:

"Note" This is usually sometimes possible, not on the occasion. I was never able to do it, but I tried it a bit.

1. Open IE Browser, click the gear graphic (i.e. settings)->internet option in the upper right.

2. Click on the connection, see the proxy server that column, will be removed;

3. Try to browse the Web (yes, failed, whining, because I did not tick, the proxy server this does not start).

The fifth type:

1. Use a different browser to browse the Web and, if unsuccessful, exclude this.

The sixth type:

"Note": my situation eventually returned to the DNS, the use of violence to resolve the method, directly manually modify DNS, although the Internet, but still do not know why the same DNS in my case.

1. Change adapter settings, network and internet-> Network and Sharing Center, Control panel

2. Right click on the wireless network connection, click Properties, click Internet Protocol version 4 (TCP/IPV4), click Properties;

3. Check [use the following DNS server address]

首选DNS服务器：   218.30.19.40备用DNS服务器：   8.8.8.8

"Note": Here the preferred DNS server IP for our city's DNS server IP, can baidu a bit; the alternate DNS server IP is a free DNS server IP provided by Google.

Also attach the national provincial and municipal DNS server IP:
