Every time I open my computer, I'm getting the following error message:

Windows cannot find RVHost.exe,make sure you typed the name correctly...

Most likely it is a virus! Could you please advise on how to remove it?

This is a is a floppy disk and network worm for the Windows platform "W32/SillyFDC-G" and installs itself in the registry. Other worms associated with Worm.Win32.AutoIt.c, Win32/Hakaglan.B.

When run W32/SillyFDC-G copies itself to the following locations:

<Windows>\RVHOST.EXE
<System>\RVHOST.EXE
<Windows>\Resources\Themes\Luna\Shell\Homestead\<o riginal worm filename>

To remove the worm follow this instruction >> (http://www.sophos.com/support/disinfection/worms.html)
