Browsing the net last night, in one of my Chrome tabs, I came across the site that popped the Chrome user information window, stating 'Stop Using Junk'. When I tried to close the tab, it would pop up another Chrome user information window with options, 'Leave the page', and 'Stay on this page'. Leave the page did nothing as it was spinning in the loop spawning new processes. I tired closing down the Chrome, but it would refuse to do it as it would spawn yet another Leave the page window. I tried to power down the MacBook, and I would get the system message stating 'Shutdown canceled by the Chrome' - since shutdown goes through kill process list, but somehow it never got there due to Chromes automatic response. Finally I stopped the network, I went into terminal and killed about 15 Chrome processes. Uninstalled the Chrome and updated to Mountain Lion thinking this could be better. Has anyone experienced such an attack?
