checksum warning - What is it?

[strick12]

When I view a report for startup entries I see several items with the following warning:

Warning: if the file is actually larger than 0 bytes,
the checksum could not be properly calculated!

What does the warning mean and should I be concerned?

Thanks,
Dana

seems that just some entries are missing detail, but i don't believe its anything to be cautious about. A spybot team member could prob. answer your question better though, but i believe that its fine and you shouldn't be concerned.
