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?
