Possible virus???

[Drew]

Opened an attachment from a friend yesterday entitled screen.com. The attachment apparently injected a program that mixes up the icons on your desktop when you place the mouse pointer on an icon, very juvenile and irritating but no more than that. I ran a Norton virus scan with 0 results. I can't figure this out and am asking....
1. Does this sound familiar to anyone?
2. How do I get rid of it.
3. I won't be sending emails to anyone until I clear up this problem so if you get an email from me...DON'T OPEN IT!!!
