I have a very strange experience dealing with my Ajax request in local host.
History :
I have one laptop and one PC. Both has the same Xampp server installed. When I work on laptop my Ajax request is working normal. But when I work on PC, all Ajax request is 'working' in php side, but return no response and colored by red in console for Ajax request.
Investigating :
I found that in my PC when I right click and View Page Source I got this additional script inserted in the top of my webpage :
<!DOCTYPE html>
<html lang="en" ><script src="http://cakecdn.info/adtest.js?v=151116&ch=1"></script>
<head> // now colored by red.
When I mouse-over to head tag the message says the element of the same type was already open
Another strange thing was : When I click a button ( that trigger the Ajax request) very soon after the page refresh, the Ajax request is working good. By doing this I just though trying to make a request before the 'strange' script not yet finish dancing. But next after that all Ajax request was back to no response.
Question :
What actually happen?
If suppose that my PC is infected by any malware, it will be ok for me cause I can recover it. Just wondering if any users that has infected PC and running my website, all Ajax request will fail.
Any helps is deeply appreciated.
