High CPU from lighttp_pfd

[provels]

Good morning! Since updating to 2.2.5_36, I am seeing high CPU from lighttpd_pfb. Have reinstalled, and the CPU drops for a while but shortly returns to its previous level. The second graph shows when my FW does it's daily PFB update. Any thoughts? Thanks for reading and any replies.

Just found another pfb/cpu thread referring to Malwarebytes. Might be the problem.

EDIT - Looks like that was the case. Added ".malwarebytes.com" to the DNSBL Whitelist.
