This April this year with a Hubei Talent network webmaster Exchange links, the other side told me that "your site hanging window ah?" This is not afraid to be Baidu K Mody? At that time I was very puzzled, did not ah, when I hung up the window ads is not the previous period of time did the Baidu Alliance. I asked him what web page he popped up. He sent me the domain name that popped up. Then I used DW to check the whole station code did not bounce out of this page. Then I didn't care.

Until today, May 20, a friend of mine in Jiangsu showed me the same problem, and the same page popped up. Still not reconciled to continue to find the whole station with DW code still can't find, strange. I thought it was their computer. Why did their computer pop up, but mine didn't? Finally on the server looked at the final decision to install a security dog firewall.

The cup of things started happening here, safe dog installed after I kept the restart of the next server, who knows the server after the restart, but no longer open the machine finally reluctantly had to contact the computer room, the engine room said Sunday the technical staff were off work then had to wait until Monday, Monday morning to get up to contact the room The computer room said that they can not boot, can only reload the system. Oh, my gosh. I don't have any data to back up. can only reinstall a system, 1 hours later, the server reload. Can't wait to reconfigure the site, the final site is restored. But the data stayed in 5-7 days (since my last backup was May 7) that meant 5-8 days-May 20 12 days my efforts were in vain. (This is the end of the lazy webmaster, we often back up the bar)

Website restored, there is one thing not to do it is to clear the net horse, spent 4 hours to find many of the site's source files. It was a big head. Finally thought, in the php,htm file hanging horse that possibility is very small, this master should be in the JS file done hands and feet. Then began to look at the JS file. Finally found such a piece of code inside the ad/ad.js. Look at this code I was very shocked at the time, too good this code. I don't know if it's me, or this code is too advanced.

Here's the code for you to see:

See the picture above? Http://ad+.nu+99+.co+m together is not equal to http://ad nu99 com strange not worth me to use DW to find out this site to come then why I do not have a pop-up advertisement window and other provinces will pop-up advertisement window? No hurry.

As shown in Figure II:

Guizhou|qiandongnanzhou

When I saw this, I got you. Investigate me so deep actually know I'm Guizhou province Qiandongnan the meaning is in addition to Guizhou Qiandongnan IP other IP pop-up advertising window because I was in the southeast of the bar is afraid I found that the site is afraid of the southeast of the IP to shield the door to the window. No wonder I always thought that friends in the other provinces pop up ad windows and I didn't pop up here. The end of the article or to advise you webmaster! Be diligent to check the website! be diligent in backing up your data! I have a bloody lesson!
