[clamav-users] Scan very slow

Hi Mark, all:

I’m disappointed to hear that it is still slow for you.

We found that the target-type of signatures used for PhishTank.Phishing signatures were causing a significant slowdown.   We have dropped them as of this past Saturday ( https://lists.gt.net/clamav/virusdb/75279 ) and in the last two updates have been re-adding them with more specific scan target types.  We’re now investigating some other optimizations we can make for the next major ClamAV release to improve scan times but at present we don’t have any other leads for signatures that may be slowing down scans.

Regards,
Micah

Cheers Steve,

In the interest of completeness, here's the scan from today (TXT from DNS: 0.101.1:58:25399:1553509741:1:63:48528:328) showing a marked improvement in scan time, although at 6m 7s it's still almost twice what it used to be.
