Meaning of Total errors on result of Clamav scan

Question

I scanned my Ubuntu computer using Clamav the following are the results

Known viruses: 2288150
Engine version: 0.97.8
Scanned directories: 55215
Scanned files: 283662
Infected files: 0
Total errors: 18736
Data scanned: 16464.40 MB
Data read: 30027.11 MB (ratio 0.55:1)
Time: 4558.179 sec (75 m 58 s)

My Question is what are total errors and I should I do some thing to remove them?

Solution

Read this Clamav faq question #21. No need to sweat.

These "errors" are not actually errors but are usually files you don't have read access to. They may belong to another user or to the System. Either way they probably aren't anything to be concerned about.

If I see this error, does this mean my Scan is not running via Root user?

What if I'm the only use on the system, have run clamscan as sudo, and have 16343 errors!?
