I am seeing the same problem. While I don't yet know how to remove the damn thing, I have at least temporarily removed the 100%CPU part of the problem by excuting "del c:\windows\system32\ping.exe & copy c:\windows\system32\mshearts.exe c:\windows\system32\ping.exe" from a cmd shell.
You have to do this in a script (I used a cygwin bash shell but a DOS .bat file should work too) as the virus program watches to see if ping.exe is deleted and creates a new copy fairly quickly - faster than I was able to match just with the file explorer.
Anyways, the result for now is that the virus program now starts mshearts (hearts) rather than ping which doesn't swamp my CPU and allows faster running of other stuff. BTW, running GMER right now which has detected a hidden/no-name module which I hope will be a big step towards getting rid of this problem.
