Has Norton found a cure for W32.Mezit!.inf?

Several days ago after a full system scan on my lap top I got the message that I had w32.Mezit!inf and it had to be manually removed.  Not being that sharp on tech skills, I have been re-scanning like every other day.  Yesterday ran the full system scan again and it finished out that "No threats present".  My queation is this. Has Norton solved this problem or am I getting a false possitive on my recent scans.  Note I said scans as I have re-run the full system scan three times, all with the same results, a clean system.  Please help!!

Thanks
