Clean install of Win 7 after wipe drive with DBAN

My computer got infected with the FBI MoneyPAK Virus and I performed the surface reformat with a OEM WIN 7 disc. Seemed to do the trick but here lately been having more issues and unable to update to SP1 and getting Windows error for malware on the machine. Norton, Malware Bytes or Trend Micro have not detected anything but I have a feeling something transferred into the Window Old folder. Anyways I attempted another surface reformat and let it do it's thing and when i returned to the computer it had a windows login screen loaded up. I've never had the computer password protected or set up multiple account on it so should just boot up to Windows desktop. The keyboard and mouse are disabled too and will not work. I'm not sure if its the case but seems like the computer is turned into a zombie or something. Anyways to the point I downloaded DBAN and copied it to a disc and changed boot device to the disc drive within BIOS. When I tried to boot using the disc it still goes to that Windows login screen and not able to do anything other then a hard reboot. I'm wanting to wipe that hard drive and do a clean install of Windows 7. Also just an FYI my boot drive is a Corsair SSD. I'm trying everything possible to not have to buy a new SSD. Any ideas, suggestions or links to step by step guides would be very hopeful. This is also my first time using DBAN. Thank you.

Try Cleaning the HD Drive, using the CLEAN command (Do not use CLEAN ALL) in Step One in this tutorial:

Then follow these steps to make sure you're getting a perfect Clean Reinstall - Factory OEM Windows 7
(same for retail).

You should not be getting a windows.old folder if the drive was actually wiped since there is no installation to bundle into it. So if you got it then it wasn't wiped. Use Clean command.

If you wiped the HD with zeroes and again with Clean and malware persists you should study the actual malware discovered as it may be a rare BIOS infection which requires reflashing the BIOS chip. Sometimes even that is not enough.

Thank you all for the replies. I finally was able to boot using DBAN, and from there did a DoD Short wipe, took about two hours and installed clean install of Win 7. Just updated to SP1 with no Windows malware error and working fine now.
