I'm running a clamwin scan of my PC and there are multiple lines stating

LibClamAVWarning:cab_unstore:bytes<0

I've not seen this before - is it a problem? I upgraded to the latest Clamwin a little while back but this hasn't shown up in scans before.

Thanks in anticipation of an explanation

It looks like ClamWin had a problem handling a Microsoft cabinet file. They used to be a bit of a problem (real slow), but I think they fixed that some time ago. That's about all I can tell you--perphaps someone else can chime in with some better help.

I have yet to se a virus hiding in .cab files, so you would probably be pretty safe in excluding that extension in your scans until you find out what's going on.

Regards,

it's a malformed cab or a cab that clamav does not handle, can you isolate it?

Hello, same thing happened to me.

Sherpya, will try to post you the scan output asap.
