[clamav-users] Different results: Clamscan vs ClamWin

[Peter B.]

Dear Clamav users,

I was scanning a ZIP file with both: clamscan (on Xubuntu), and clamwin
(on Win7).
Clamwin found a virus, where clamscan did not.

I'm surprised, since I thought these are just 2 frontends for the same
engine and virus database?

I updated the database on Linux using "$ sudo freshclam".
No change.


Grateful for any information why clamscan finds less than clamwin...? :)

Thank you in advance,
Peter B.
