My Avast virus scanner finds the trojan Win32:Trojan-gen.{VC} in dieorlivesetup.exe, a program published by Mr. Lyu shuzhi, 67 Meihuacun, zhongshan rd.1, Guangzhou, China.
This program comes with the Go software I purchased, Many Faces of Go v. 11.
This is the only virus found on all my 13-odd harddisks. I hope the virus checker is wrong!
