This afternoon the isearch search tool appeared just above my toolbar. I searched around for a solution (not here, unfortunately!!!) and found that the software designer had a website with a tool (http://toolbar.isearch.com/uninstall/). I downloaded the tool, ran it, and rebooted my computer.
Well, for over an hour it has been saying that it is updating my system settings. I can get on the computer through Safemode but don't know what to do. And in Safemode I can't access the internet to download any of the tools from this site that might help.
Any suggestions would be very much appreciated. I've looked for new software and removed anything that didn't look kosher.
