Have a question. I scanned a backup the other day with Norton Antivirus Corporate (v8)yesterday and did not find any viruses in the files that I scanned. I transferred the backup to my local machine and scanned it with Norton Antivirus 2003 Personal Edition and it found several files that were infected with the Klez virus. Has anyone else had this problem? Both sets of Antivirus had the latest definitions installed. The Norton Corporate machine is a Win2k Server and my local machine in Win2k Pro.
