My isp just sent this warning and since this virus looks like it's coming from the FBI, it might be tempting to open:

Darbie, I agree! If they had to plan a cruise they wouldn't have enough time for virus making :)

Thanks, Karen.

People are so gullible to think the FBI would send out mass emails. It never ceases to amaze me.

Thanks, Karen. Dave gets up in the middle of the night and logs on. If you're tired, you may not be thingking clearly.

Thanks for the warning, Karen! I am sure I would be suspicious, but you never know.
