I installed Fiddler 4 Beta to do some HTTP tracing. I found a lot of calls being made to sites like : facebook, collegehumor and a bunch of other sites I've never visited. Could not trace what/who is initiating these calls as I do not see any Windows Processes. No one else is connected to my network. I use both Google Chrome and IE10 on a Windows 7 box. Please help me tracing and removing these malicious HTTP calls.
