Odd - I had no issues - then right after I visited this thread - MSE popped up with a warning - here's the details:
Encyclopedia entry: Adware:Win32/Hotbar - Learn more about malware - Microsoft Malware Protection Center
Then I ran Malwarebytes - 4 infections. I can't guarantee they are coming from here - but I never have issues like this. Curious.
