Nessus always cites our workstations with a HIGH vulnerability = "Cisco WebEx Extension for Firefox < 1.0.12 'atgpcext' Library GPC Sanitization RCE (cisco-sa-20170717-webex)"

We have tried to remove all traces of the Cisco WebEx Extension (1.0.9 >> 1.0.12) from our workstations ||| Firefox 54.0 (x86 and x64) or Firefox 55.0-.02 (x86 and x64).

We have uninstalled/reinstalled Firefox, deleted Mozilla/Firefox directories, ran the Cisco Meeting uninstaller, ran CCleaner, scanned the Windows registry looking for elements, checked %AppData%

NOTHING IS WORKING TO FIX THE VULNERABILITY - Please assist! Thank you, Michael

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
