Is Adtarget malware or clean?

Hi,

Seeing this on our firewall for a few users.

"sync.console.adtarget.com.tr"

Firewall lists it as malware, threat name CnC, detect method infected domain. It appears to be tracking perhaps? Anyone familiar with it? I am pushing full antivirus scan on all systems, and ran malwarebytes on at least one system that was detected with this, and scans found nothing. loginjet

Thanks in advance for your help.
