I get the same problem, but Astaro are saying that no-one else is seeing the problem. Could you make sure that you report this bug to Astaro so that they know it is not specific to just one installation.
I've got the same problem this morning. Also the contend manager does not show the type of virus anymore. When i move the mouse over the identifier nothing happends. Can You confirm this on your machine?
I have a temporary solution proposed to me by Astaro support. It seems the bug is in the ClamAV scanner, so switching this off and just leaving Kaspersky on might alleviate the problem until 6.102 is released.
Also Astaro have confirmed that can now reproduce the problem and therefore it should be fixed shortly.
