BleepingComputer.com: False positive report

I did a scan with Norton Internet Security 2011 and received a report that no security risks were detected. But number of items scanned was on 235,000; the number in the past has always been around 750,000. Something must be truncating the scan. I repeated the scan; same result. I downloaded & ran Norton PowerEraser; no risks found. I've tried to get into the Norton Forum, but while my registration was confirmed on the registration page, confirming email was never received. Next step?

Check you scan settings. It's possible you inadvertently changed something whereby the scanning engine is not scanning everything it did in the past.
