Hello there Lucky Man

Please try a couple of these free online scanners to see if anything has slipped by your protection:
(Be advised that some of these scanners will pickup things in "quarantine" from other anti-virus programs - so review the results carefully)

If you find that you're infected (or the scan doesn't complete or closes unexpectedly), post in the Am I Infected forum located here: http://www.bleepingcomputer.com/forums/forum103.html
