No, you don't need to post any more-
there is surely no doubt about Ramnit! It's too bad you didn't follow up on the previous thread. This is no new infection- it appears that about everything on the system is infected with Ramnit. I hope you have the files you didn't want to lose already backed up because it doesn't look like there's much left and the system has been badly compromised.
This is what Jesper M. Johansson at Microsoft TechNet has to say:
Help: I Got Hacked. Now What Do I Do?.
The only way to clean a compromised system is to flatten and rebuild. That’s right. If you have a system that has been completely compromised, the only thing you can do is to flatten the system (reformat the system disk) and rebuild it from scratch (reinstall Windows and your applications).
Important Note:: If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned.
All passwords should be changed immediately to to include those used for banking, email, eBay, paypal and any online activities which require a username and password. You should
consider them to be compromised. You should change each password using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach. Failure to notify your financial institution and local law enforcement can result in
refusal to reimburse funds lost due to fraud or similar criminal activity.
