Using Norton AntiVirus, I did a manual scan of my Mac hard drive and LaCie external hard drive. The Mac scan went well. I have the LaCie external partitioned into 2 parts, one for the Mac Time Machine backup.
When I did a separate scan of this Time Machine backup, Norton reached the point where it had scanned all the files, but then it kept going, scanning more files than it said were on the backup partition. I finally had to cancel the scan.
Why did this happen? What should I do about it? Thanks.
