In sorting out all the ISO's I aquired ... I found 2 copies of Windows 7 OEM doing the rounds Code: 7600.16385.090713-1255_x64fre_client_en-us_OEM_Ultimate-GRMCULXFREO_EN_DVD.iso 2586bce75eef8e13e8b35347b01d03c340565d27 7600.16385.090713-1255_x64fre_client_en-us_OEM_Ultimate-GRMCULXFREO_EN_DVD.iso 82C8C36423A1511516E54DC7E54B96603AA88F01 I downloaded both to see ... and the one with a hash of 2586bce75eef8e13e8b35347b01d03c340565d27 was modified by UltraISO. Been curious as to why somebody would modify the image I decided to look closer. The SETUP.EXE file in the root of the DVD image was 198332 bytes, whilst it should be 106760 bytes. I tried to extract the file from the ISO to look closer, but my Anti-Virus was set off... Injector.ABU Trojan So if you have an ISO with the above hash, or your burned disc contains the above setup.exe - bin it. I've searched on the hash of 25.... and I find references to it on the internet but no mention that it's a virus infected copy.
