Yes, scanning this 2MB files that it is a .eml file with some .pdf attachments hangs.
I tested in Windows XP SP1, Windows XP SP2 and Windows 2003 in all this PC´s do the same. And I found this.
For example:
You run clamscan.exe to scan this file FileThatHangs.eml.
ClamScan hangs with a 100% use of CPU for ever.
If you go to the tmp directory and open the direcotry that ClamScan created inside tmp direcotry (example: clamav-4723c7ee7ca68f9d654654a9ce12dd9e) , automatically ClamScan stops and return an error like this.

LibClamAV Error: Can't remove temporary directory /cygdrive/c/clamav-devel/tmp/c
lamav-4723c7ee7ca68f9d654654a9ce12dd9e: Device or resource busy

What is happening, only found that it does it with this eml.? Are .pdf the problem? Why it can´t delete the tmp directory, with any other files work perfect.

Any idea. I give you to all this file to donwload it and confirm, what I am saying.

I don't hqve this error in 0.88
Do you have "Treat files as mailboxes" enabled in the advanced settings?

Sorry, but clamd.conf doesn´t habe any option like "Treat files as mailboxes".

Thanks.

I was talking about clamwin configuration, not clamav. clamscan parameter for not processing rfc822 files is --no-mail

If you are using clamd and clamdscan then you are in a wrong forum. ClamWin does not support clamd and it does not include it in the distribution.
If you are using SOSDG port please contact them for support.

yes. Wrong forum. jejejejeje

Thanks for all.
