[clamav-users] invalid icon entries?

[Tom]

When I run clamscan (clamav-0.98.4-1.el6.rf.x86_64), I get this output:

LibClamAV Warning: cli_scanicon: found 3 invalid icon entries of 3 total
LibClamAV Warning: cli_scanicon: found 3 invalid icon entries of 3 total
LibClamAV Warning: cli_scanicon: found 12 invalid icon entries of 12 total

Are these infected files? If so, how can I get rid of them? If not, how 
do I deal with these warnings? Thanks in advance...
