iTunes Trojan Horse Small.bog

AVG antivirus users around the world were quite alarmed to learn that iTunes.dll and iTunesRegistry.dll in their computers are infected with “Trojan horse Small.BOG”. AVG antivirus just sort of identify iTunes files a virus. People who are not using AVG antivirus did not have any problem at all. So it comes out that AVG antivirus somewhat malfunctioned? AVG and Apple are of course flooded with user experiencing the so called iTunes Trojan Horse Small.bog, users want to know if this Small.bog something is really a threat to them. I guess someone in AVG is going to get fired.
