Beware of new virus tricks.

Most of us here probably know the trick of using a double extension, hoping that the second extension is hidden by default: Sample.txt.exe; the user might see Sample.txt.

Today I got a virus that uses an interesting variation of this trick, with a name like:
test.jpg               .exe
... or some other executable extension. Note that there are lots of spaces in the filename. All this comes within a ZIP file.

The EXE extension might easily be overlooked in this case; it might even be invisible, depending on the column widths in your decompression program.
