I tried scanning /sys, and it gave me the same messages, but I don't think it's a bug per se. It's more likely because /sys is a 'virtual' directory, and it has a lot of special files, clamscan gets confused while scanning it. If you run 'top', you'll see that clamscan is indeed working hard to scan some of those file (like 99-100% CPU usage for clamscan process).

You could try excluding /sys (and possibly /dev ?) from scanning with the command-line option:

       --exclude=REGEX, --exclude-dir=REGEX
              Don't scan file/directory names matching regular expression.
              These options can be used multiple times.

See if this helps.

Agreed with the option outlined in comment 2. Marking this bug as Invalid.

Thanks,everyone.

Mr.Gergely
Thank you.
I tried the way that you taught and could scan with no problem.

Mr.Gug
Sorry and thanks to correct my reports…….
