Is now recognizing bitcoin-miner.exe from th GUIminer file as a threat.
Ikarus (the av engine I use) labels it as "possible-Threat.Win32.BitCoinMiner", they originally labeled it as a Trojan but changed it to "possible threat" after many submitted it for analysis.
They do this to alert people who have no idea what bitcoin is that there is an issue happening on their machines.
