malware keeps opening new tabs

Have this malware that keeps opening new tabs, randomly. 
 
one was betrad, and the other one was something else,  s.arlime.com  or something
for the betrad, from my research it was in the flash cache which i cleared.     Still getting new tabs. 
 
Full scan with webroot, nothing
I spent 8 hours per one scanning with malwarebytes and  adaware and spyware searchu and destroy ... Nothing.
 
I tried watching the webroot logs on chrome,  So I clicked on a link from skype. 
there was a bunch of dlls sent to chrome and the new tab opened from skype.
 
So i'm not sure how to follow those event logs.   I tried searching with the process id, but none of the numbers were from skype.
Nothing looks funny in the process list, and services.msc     Is there anyway to track this thing down, so I can submit it to webroot? 
usually malware is pretty obvious, but this one is probably super new...   
 
 
The issue is, it opens up new tabs randomly at random times...    And then webroot will tell me that the pages have been blocked.    Like i'll be playing a game and it'll popup.       
 
It would be nice to figure this out before I re-install windows.   :)
