crl.verisign.com Threat Protection false positives?

stealthmatt_01
Hi all,

We are seeing an increase in ATP notifications just today, in relation to *crl.verisign.com

This seems like its a certificate look up? Mulitplie UTMs are reporting this same threat with different clients, we have run malware bytes and full system AV scan and can't seem to find anything.

The one PC we did find a trojan, we have cleared and just now it has said the same IP tried to get to the same site? the Reason is both DNS and Proxy...
