MSRBL-Spam issues

[Allan Spencer]

This morning around 7am I was met with a looping MS Server so after 
doing a --debug --lint found the following

LibClamAV Error: cli_hex2str(): Malformed hexstring: 
687474703A2F2F7777772E77656262616E6E6572736F6E6C696E652E636F6 (length: 61)
LibClamAV Error: Problem parsing database at line 2746
LibClamAV Error: Can't load /usr/local/share/clamav/MSRBL-SPAM.ndb: 
Malformed database
ClamAV Module ERROR:: Could not load databases from 
/usr/local/share/clamav at 
/usr/lib/MailScanner/MailScanner/SweepViruses.pm line 548

Delete the file and tried a manual reupdate but still does the same 
thing so deleted it for now and disable cronjob. Just wondering if 
anyone else has seen this ?

2 days ago upgraded to 4.71.10 but other than that nothing changed, 
Centos 4.6 SA & Clam package off the MS site and no yum updates

Any suggestions or assistance

Thanks
Allan
