On July 28 the Internet Explorer 8 was attacked by the fake virus AV Shield. Could no longer connect to the net. Switched to the backup browser and no problem I deleted Explorer 8 and tried to re down it, would not download. Tried with Google Chrome same issue. Now I have a yellow shield with a black exclamation mark in the right lower corner stating that updates are ready to download. However Microsoft Essentials state that there are no updates to download. Since the exclamation mark is black instead of red could this be part of the fake virus trying to download, and how can I get rid of it.
