Virus/bot/hacked on new MacBook Pro
Hi, I purchased a new MacBook Pro in December 2012.
I use the native browser - Safari and no other browser. Version 6.0.2 MAC OS 10.8.2 and I use COMCAST for email through a browser.
Every few minutes a box appears on my display too fast for me to see it and disappears. A few weeks ago COMCAST emailed me a notice saying I might have a bot but I can't reach their technical support line. It's also not clear it was genuinely from COMCAST.
I installed Clamvox and Sophos, neither have found any virus..
Can someone please help me? I can't figure out what this mysterious pop up is and I can't see it long enough to know what it says. COMCAST is not helpful.
Thank you.
