What exactly are Twain and Twunk? I think they're probably something to do with Lexmark, but I'm getting conflicting messages as to whether they're healthy or not. Tom Drane
Twain is a standard system for talking to scanners and digital cameras (http://twain.org/). Twunk_16.exe and Twunk_32.exe are usually legitimate Twain files. However, the Blackmal.C trojan also uses these filenames to avoid detection: Symantec has details. You can tell from part 4 if your version is malware. Otherwise, most anti-virus products should pick it up. Double check using SuperAntiSpyware.
