The remote host is missing an update to clamav announced via advisory USN-770-1.

The problem can be corrected by upgrading your system to the following package versions: Ubuntu 9.04: clamav-milter 0.95.1+dfsg-1ubuntu1.2 In general, a standard system upgrade is sufficient to effect the necessary changes. https://secure1.securityspace.com/smysecure/catid.html?in=USN-770-1

A flaw was discovered in the clamav-milter initscript which caused the ownership of the current working directory to be changed to the 'clamav' user. This update attempts to repair the incorrect ownership for standard system directories, but it is recommended that the following command be performed to report any other directories that may be affected: $ sudo find -H / -type d -user clamav \! -group clamav 2>/dev/null Systems configured to run clamav as a user other than the default 'clamav' user will need to adjust the above command accordingly.
