There is a program on our local talk radio on Saturday mornings called, "Get Connected with Mike Agrabo."
On his web site there is a warning to be had for April 1st (not April Fool's) it is just good advice.

Don't be a Fool on April 1st
By Claire Dumican
The first week of April typically brings an increase in new spyware infections. It’s become something of an annual tradition that causes havoc for computer users: lost productivity, overall inconvenience and the potential of thousands of dollars in repairs.
What can you do to protect yourself from spyware and malware?
-Be extra cautious opening emails, particularly files or attachments, from people you don’t know.
-Don’t be fooled by “scareware” tactics. Know what software you are using, and familiarize yourself with how it delivers warnings and alerts.
-Stay away from websites that you haven’t visited before. Think before you click!
-Run multiple layers of security software. There are many free and effective solutions that will co-exist well with each other. Remember, a single solution may not be enough, especially during this period of increased spyware activity.
