hxxp://download-upload2.com/index.php?key=anti%20virus%20trojan

Yesterdays link for download hxxp://download-upload2.com/2_setup.exe

Todays link for download hxxp://www.adsame.com/adsamer2/eaglepro/system ... setup.rar

Both downloads though is Zeroaccess

I was really surprised at the accuracy with which Microsoft recognized droppers of ZeroAccess/Sirefef and Tdss/Tidserv in it's malware-thread. Have experienced this many times and almost always the result is right. I think no one vendor can boast of such accuracy add of these droppers (Alureon and Sirefef).

Even if you take the last VT-links, published by rough_spear, you will see this result:

96be7f02a6319bb5ee33725007c96c0e -> TrojanDropper:Win32/Sirefef.B, 2011-09-23
9e65e8dc1bb7e83b61cef5076acb5ffd -> TrojanDropper:Win32/Sirefef.B, 2011-09-23
ddf3e4c97f00f55b1911eb86552fcaa8 -> no detection
9ed99fc2195505bec40b56c7989dc110 -> TrojanDropper:Win32/Sirefef.B, 2011-09-24

Detection by other vendors in this case as "generic". By the date (addition rate) I think that it robot working.
EDIT: date info
