I and my daughter are using ESET NOD32 V3 Anti Virus. Last night her PC started acting very strange. She cannot connect to the Internet and she has seen her screen display the file name of kaka.exe which according to my Google search is a Trojan. She has the lastest ESET virus definitions on her machine. Should her ESET NOD32 V3 Anti Virus have detected this kaka.exe? She ran a deep scan last night but nothing was detected. How can she get rid of this virus? Thanks very much for your help!
