I have just recently been getting weird entries on my security history page. It's severity is marked as "info" the activity is "Statistical Submission: WS.Trojan.H Exonerated" status pending. There are a couple that are the same, but there are several others with different descriptions. What does this mean, has my computer been infected and norton does not know if it is truly a virus? This all happens during or after i do a system scan, the scan when finished says all is good.
