Hey,i found this file which has the same MD5 with the one you posted,it is here
https://www.virustotal.com/nl/file/d87bfda9ac76f7e894bafb75b8eb66447e596abe638683fbb65b82228ea286a2/analysis/1383131752/
It’s pretty much the same file but this one is detected 8/47.
Apart from that they share the same original file name which is hao123Inst.exe
You can find more info here http://regrunreanimator.com/newvirus/trojan/hao123inst-exe-2.htm
The file HAO123INST.EXE is identified as the Trojan Program that is used for stealing bank information and users passwords.
Also Ikarus detects the file as Trojan.Win32.Spy .
It looks like an “evil” thing to me ;D
