hi
I think you can resolve the issue by involving fork() processes as they might run diff. set of processes in background.
Thanks

clamav-unofficial-sigs(8) SCRIPT COMMANDS clamav-unofficial-sigs(8) NAME
clamav-unofficial-sigs - Download, test, and install third-party ClamAV signature databases. SYNOPSIS
clamav-unofficial-sigs [options] DESCRIPTION
clamav-unofficial-sigs is a shell script that updates the Sanesecurity, SecuriteInfo, MalwarePatrol, OITC, INetMsg and ScamNailer third- party signature databases for ClamAV. OPTIONS
This script follows the standard GNU command line syntax. A summary of the options is shown below. -b Add a bypass signature entry to local.ign in order to temporarily resolve a false-positive issue with a third-party signature. The script will monitor any entries it makes to local.ign and will automatically remove bypass entries if either the original signature has been modified or removed from the database. -c FILE-NAME Source configuration information from a different file. -d Decode a hexadecimal encoded string or an individual ClamAV 3rd-party signature for viewing. This will not decode image signatures nor the official signatures. -e Encode a entire input string in hexadecimal for signature usage in any *.ndb database. -f Encode a formated input string in hexadecimal that contains spacing field '{}, (), *', without encoding the spacing fields, for sig- nature usage in any '*.ndb' database. -g FILE-NAME Verify the GPG signature for a specific SaneSecurity database file. Only specify the filename as listed in the configuration file and the script will search for it in the work directory. -h Print the script help and usage information. -i Print system and script configuration information. -m Make a hexadecimal signature database file (*.ndb) from a clear text ascii file. Provides support for both full and formatted sig- natures. Additional information is provided when using the flag. -r Remove the clamav-unofficial-sigs script and all of its associated files, databases and work directories from the system. -s FILE-NAME Test the integrity of a third-party signature database with clamscan. Only specify the filename as listed in the configuration file and the script will search for it in the work directory. -t If HAM directory scanning is enabled in the script's configuration file, then output the names of any third-party signatures that triggered during the HAM directory scan. -v Print the script version and date information.
