[PATCH] clamav: Create backup of signature files

[PATCH] clamav: Create backup of signature files

[Michael Tremer]

[-- Attachment #1: Type: text/plain, Size: 1997 bytes --]

After clamav is updated, the signature files need to be
re-downloaded. This is often unnecessary and delays restarting
clamd, squidclamav and other dependent services.

This takes a long time on slow internet connection and transfers
about 110MB of data.

This change will backup these files and freshclam will update
or re-download them only if necessary.
