Updated antivirus will only catch specific instances of POC code, not any actual reallife exploitation which easily differ significantly in footprint and signature. It's been a constant nuisance the last few years that whenever you release any kind of POC the AV vendors will label it as a virus and have their customers feel safe whenever they try to demonstrate publicly available POC code, while still doing nothing to hinder exploitation of the actual vulnerability. AV vendors should realize that their approach to security often will lead to greater insecurity, I have no count of the number of people writing me and telling me they would not install a potentially systemdamaging patch since my public POC didn't work anyway on their system because of their superior AV product. Out of sight, out of mind..
