Comment 5 for bug 366572

The clamav update you tested is in Jaunty updates now, so clamtk should have sufficient permissions to get signatures to update for each user (the single user option). I did test this and find that it had the signatures and could find the clamav test files.

If you look at the screenshot you provided, you can see a green check mark next to signatures. Also when you use the check updates function is will check and finds it has current signatures. So I see this as a user interface problem, the actual functioning of clamtk (and clamav) is fine.

The problem (as you point out) is the 'None Found'. This is inaccurate and will certainly confuse and concern users, but doesn't appear to affect clamtk's ability to find a virus.
