Frequent pop ups from Malwarebytes blocking wpad.browsersecurity.info

My Computer Running Windows 7 started showing issues about internet connection - The Proxy server Not responding. The device or resource (web proxy) is not set up to accept connections on port "8080". The issue was fixed when I ran a full scan in Malwarebytes (Other Ant-virus/malware like MS Security essential or 360 Total Security couldn't help).

But whenever I am connected to internet, Malwarebytes gives pop-up - Malicious website blocked - wpad.browsersecurity.info. 

IE still shows error - The Proxy server Not responding.

I already ran many anti-malwares like RogueKiller, Combofix, FRS, SUPERAntiSpyware etc when i was going through some similar issues in this forum. But nothing could help and detect/remove that malware.

Registry also not displaying any wpad.browsersecurity.info values. Similar softwares are not found in control panel / browser extensions. 

Since you have run RogueKiller and ComboFix...please follow the guidance at Preparation Guide, Before Using Malware Removal Tools and Requesting Help - http://www.bleepingcomputer.com/forums/topic34773.html .

Note that the new topic is to be posted in the same forum containing the Prep Guide, not in the Windows 7 forum.

Thanks.
