Darwine comes from the project Wine, which provides UNIX environment running Windows applications.
After installing Darwine, plug the virus infected U disk, however, Mac won’t get infected. But you don’t double click the virus file, probably it would execute. Really!
But don’t worry, UNIX structure would protect your system from great damages.

First download Darwine, go to the next address:
http://www.kronenberg.org/darwine/
There’re two versions, one is stable version 1.0, the other is unstable version 1.1.2, and I suggest you download the 1.1.2, as I know about Wine, no matter which version, Wine always has many bugs.
If Tiger, you’d have to install xl1.

Download that and then drag the Darwine folder to the Applications.
Next let’s set up:
Enter the folder Sample WineLib Applications under Darwine folder, and double click to run winecfg.exe, which would auto establish your Wine environment. This step is necessary; when finish, there’s a folder in the primary folder: wine, as it’s hidden, so you could not see it. please ope the primary folder, and in the Finder menu, choose “Go up to”, “Go up to folder”, manually type .wine then you could enter it.
Here you would see a driver_c folder, which is the drive C you make up, double click to enter.
Probably just now you noticed that the contents of the application winecfg.exe are all disorder code, as there’s no Chinese Fonts, so we need to copy Microsoft YH fonts (MSYH.TIF MSYHBD.TIF) to current folder—Windows—Fonts, open the terminal and keyed:
1. cat > cn.reg
And then copy the contents below
