If I go to Gmail's homepage or other pages, Microsoft Security Essentials keeps popping up the potential thread of "Exploit: JS/Blacole.Bw" with alert level as "severe." I did malwarebytes and Trendmicro both of which have deemed my PC to me clean and fine..is this an error or glitch? Can anyone help and why does Microsoft Essentials only detect it? Any clue on how to remove it? Please help if so, and thank you in advance.
