You're infected with Ramnit file infector virus. It's not curable.
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.
