Managed to get some detailed information regarding this virus. As I say, its one of the worst ones you can get
Like I said, sometimes you can remove all infected files, it just depends on how deep the infection is, which in your case, I think its still there.
Ramnit
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. 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 smörgåsbord of malware and a major source of system infection.
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. For more info, please read:
