That is why several antivirus programs have become huge sandboxed network-snooping "big brother" suites that bog down computers (while still not very effective).
This is also why most companies that do secure computing put TWO computers on their employees desktops (one connected only to the internet for email and web browsing, and the other connected to the internal secure LAN for mission-critical apps), and they have VERY strict guidelines about what can be installed on computers connected to the internal network.
So, PROBABLY a false positive.
