W32.HLLW.Suava

W32.HLLW.Suava is a worm that has two components:

• A file that downloads the worm/backdoor from a Web site
• The worm/backdoor itself

The downloader downloads a file from a Web site to %Windir%\Fb.exe, and then executes that file. It also creates a copy of the downloaded file as C:\Windows\Mspread.exe.

W32.HLLW.Suava attempts to spread to the network shares.
