Somehow I doubt any of these files are actually virii.
Code:
//usr/portage/distfiles/clamav-0.88.1.tar.gz: ClamAV-Test-File FOUND
//usr/share/apps/krita/templates/gray/.source/white_640x480.kra: Oversized.Zip FOUND
//usr/share/apps/krita/templates/rgb/.source/transparent_1280x1024.kra: Oversized.Zip FOUND
//usr/share/apps/krita/templates/rgb/.source/transparent_640x480.kra: Oversized.Zip FOUND
//usr/share/apps/krita/templates/rgb/.source/white_1024x768.kra: Oversized.Zip FOUND
//usr/share/apps/krita/templates/rgb/.source/white_640x480.kra: Oversized.Zip FOUND
//usr/share/apps/krita/templates/rgb/.source/transparent_1024x768.kra: Oversized.Zip FOUND
//usr/share/apps/krita/templates/rgb/.source/white_1600x1200.kra: Oversized.Zip FOUND
//usr/share/apps/krita/templates/rgb/.source/transparent_1600x1200.kra: Oversized.Zip FOUND
//usr/share/apps/krita/templates/rgb/.source/white_1280x1024.kra: Oversized.Zip FOUND
anyone have any Idea whay they are showing as positives? should I report what I assume are false positives to ClamAV?

From http://www.clamav.net/faq.html.

I get many false positives of Oversized.zip

Whenever a file exceeds ArchiveMaxCompressionRatio (see clamd.conf man page), it's considered a logic bomb and marked as Oversized.zip . Try increasing your ArchiveMaxCompressionRatio setting.



The other entry is a test file so shouldn't be a problem

yeah I kinda figured the one was a test. but I asked anyways. I was just surprised when I got 10 positives. Last year around this time different version of clamscan I didn't get a positive on a test files so I was wondering.
