Woweee! I'm sitting here in Cuenca with Rich and Nancy, open my email, and get three Trojan horses from locals...yikes...
OK, all of you out there...if you get an email from a friend with nothing personal, but just see a big fat website, AND it says "check it out" etc...DELETE IT! DO NOT OPEN ANY EMAIL THAT DOES NOT HAVE A PERSONAL MESSAGE JUST FOR YOU.
I am no guru, but if you do screw up your system, try doing a "system restore" . I usually opt for the date for restore as the oldest one I can. You may be able to undo bad things...good luck again.
