Hello,
I'm hoping someone will take the time to read this whole thing. I'm not knowledgeable about how popular this Ban list is, firehol_level3 has your update server listed as an active viral / spyware attack point. firehol appears to be an aggregate of popular ban lists.
Details about the list:
http://iplists.firehol.org/?ipset=firehol_level3
Direct link to plain text list:
https://raw.githubusercontent.com/firehol/blocklist-ipsets/master/firehol_level3.netset
Your server I am referring to:
upgr-mmxvii-cl-ts.2d8cd.cdn.bitdefender.net [72.21.81.253]
The ip is in the ban list. This is causing repeated update fails, I believe this list is used by a number of firewall blocking tools (like pfBlocker).
Is there an alternate server I could use that doesn't appear in a ban list?
Any help appreciated!
