Free Online Independent Malware Scans

Try a couple of these free, online scanners to see if anything has slipped by your protection (most require that you use Internet Explorer):

Having difficulty with running the scans using IE9? - some scans are being updated by the manufacturer

If you find that you're infected (or the scan doesn't complete or closes unexpectedly), post in the malware/security forum
If you're not infected, post back in the original location and we'll try some more stuff.
