Summary
Win32/Ramnit is a family of multi-component malware that infects Windows executable files, Microsoft Office files and HTML files. Win32/Ramnit spreads to removable drives, steals sensitive information such as saved FTP credentials and browser cookies. The malware may also open a backdoor to await instructions from a remote attacker.
seems to be a fileinfector and that is usually very bad news
