Hi Tony
Unfortunately, even though you couldn’t send the result of the full scan, the partial scan showed the presence of a serious viral infection known as
Ramnit..
At this time Ramnit can not be cleaned and the only option is a reformat,
not just a windows repair install.
Infection information
Win32/Ramnit is a file infector 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.
Why the only sure way to remove it effectively is to reformat and reinstall the OS.
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 damage can vary.
In most instances it may have caused so much damage to your system files that it cannot be completely cleaned or repaired. Security vendors that claim to be able to remove file infectors cannot guarantee that all traces of it will be removed as they may not find all the remnants. If something goes awry during the malware removal process there is always a risk the computer may become unstable or unbootable and you could loose access to all your data.
Here's a write-up:
Because your computer 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.
I would suggest you do this: • use another, uninfected computer to change all your internet passwords, especially ones with financial implications such as banks, paypal, ebay, etc. You should also change the passwords for any other site you use.
• call your bank(s), credit card company or any other institution which may be affected and advise them that your login/password or credit card information may have been stolen and ask what steps to take with regard to your account.
• consider what other private information could possibly have been taken from your computer and take appropriate steps
When you’ve done the above, reformat the system partition and reinstall Windows – it is the only 100% sure answer.
• When should I re-format? How should I reinstall?
• Where to draw the line? When to recommend a format and reinstall?
I'm sorry not to have better news but the fact that you had a
Virut infection is probably the reason that you have become re-infected.
Please let me know if you have any more questions or if I can close this thread.
Thanks
