Solutions to DNS failures caused by virus software

Solutions to DNS failures caused by virus software

The problem is that the DNS is invalid and the ping to the domain name always fails.
Today, at work in the morning, I found that the git that comes with Eclipse is always unable to update the code. I tried it more than 10 times before and after, but all failed. The prompt"Cannot open git-upload-pack ". Baidu found no similar information as my questions. Finally, I had to read the log printed by Eclipse.
Java.net. UnknownHostException", Git does not know this host.
The following are 10 solutions I have tried:

2. log out of your computer.

8. Network diagnosis

10. different projects and projects of one Eclipse.
Finally, I found the answer on Hexun's blog:
