Hi moooose,

This is Mike from the Norton Authorized Support Team.

Your system could have an infection, a software conflict , or a hardware problem. Make sure that you are using Norton 360 2.0 and not 1.0. If your subscription is valid, you are entitled to a free update to Norton 360 version 2. To update, make note of your current activation key and (using Internet Explorer 5.5 or higher) visit the Norton Update Center.

Norton Update Center

If you are already using version 2, manually run LiveUpdate to make sure you have the latest definition and product patches applied, and then perform a "Comprehensive Scan" to check for infections.

Make sure that the Windows Firewall and Defender are disabled and that you do not have any other anti virus or internet security applications installed to avoid conflicts.

If your scan comes up with no infections found and you have made sure that you do not have conflicting software, run the Windows "chkdsk" program 2-3 times to make sure your hard drive is not failing.

Thank you,

Michael York
