The log you`ve posted indicates that your system is infected with Ramnit, that infection really is bad news and has no way back, it has a devastating effect on your system because of how it works and what it does. I dont think anything can be recovered and classed as safe.

Please read the following script, especially the four links at the end.

Win32/Ramnit.A is a file infector with IRCBot functionality which infects .exe, and .HTML/HTM files, and opens a back door that compromises your computer. Using this backdoor, a remote attacker can access and instruct the infected computer to download and execute more malicious files. The infected .HTML or .HTM files may be detected as Virus:VBS/Ramnit.A. Win32/Ramnit.A!dll is a related file infector often seen with this infection. It too has IRCBot functionality which infects .exe, .dll and .HTML/HTM files and opens a back door that compromises your computer. This component is injected into the default web browser by Worm:Win32/Ramnit.A which is dropped by a Ramnit infected executable file.

With this particular infection the safest solution and only sure way to remove it effectively is to Reformat and reinstall the OS.

Why? The malware injects code in legitimate files similar to the Virut virus and in many cases the infected files (which could number in the thousands) cannot be disinfected properly by your anti-virus. When disinfection is attempted, the files often become corrupted and the system may become unstable or irreparable. The longer Ramnit.A remains on a computer, the more files it infects and corrupts so the degree of infection can vary.

Ramnit is commonly spread via a flash drive (usb, pen, thumb, jump) infection where it copies Worm:Win32/Ramnit.A with a random file name. The infection is often contracted by visiting remote, crack and keygen sites. These type of sites are infested with a vast variety of malware and are a major source of system infection.

In my opinion, Ramnit.A is not effectively disinfectable, so your best option is to perform a full reformat as there is no guarantee this infection can be completely removed. In most instances it may have caused so much damage to your system files that it cannot be completely cleaned or repaired. Further, your machine has likely been compromised by the backdoor Trojan and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if your anti-virus reports that the malware appears to have been removed.

Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

When should I re-format? How should I reinstall?

Where to draw the line? When to recommend a format and reinstall?

Backdoors and what they mean to you

http://technet.microsoft.com/en-us/library/cc512587.aspx

The only way forward with this infection is to re-format your hard drive and re-install your system. Let me know what you want to do.

The following files are definitely affected .exe/ .dll/.scr/.htm/.html/.xml/.zip/.rar

The following files are supposedly unaffected by Ramnit .doc, .txt, .mp3, .jpg If you are going to use a Flash drive to transfer any recoverable files you must take some precautions. Run the following on your clean computer, and make sure you insert your flash drives at the prompt.

Download and Run FlashDisinfector

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.

Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.

Ramnit really is bad news, you can attempt to clean it but you will never be able to trust the system. Dont forget any sensitive data may have been collected, Any passwords you use online should be changed from a known clean computer. If you`ve used Credit Cards, online banking, PayPal etc etc those details may be compromised also.

I wish I could have given better news, but that is one nasty infection that unfortunately cannot be fixed successfully...
