Well, I copied my scan log for the nod32 support group and got a very good reply which makes everything clear. This portion of it explains:
An ESET Customer Care Representative has updated this case with the following information:
Hello,
This is normal and will appear every time you run a scan. These files can't be scanned by NOD32 due to one or more of the following reasons:
1. The file is password protected (e.g. there are multiple user profiles on the computer).
2. The file is a Windows system or program file.
3. The file is currently in use by other programs or background processes.
Basically these blue lines are just informational, threats will appear in red. It should be noted that all anti-virus programs are unable to scan these type of files. The difference is that NOD32 notifies the user.
Please let us know if we can be of further assistance.
Best regards,
ESET Customer Care
So there you go.................no worries.
