Yes.  My save as renamed it, still has about 30k of tabs in it.  But I 
pulled it again, using the 'raw' link, saved it, no extra tabs.

But it still doesn't work for linux.  My python is 2.6.6

If only it would...  Using this version, the failure is silent and instant.  
Besides, the malware could be anyplace on the system.  But it needs to skip 
/dev since it hangs on the midi tree, /mnt and /media because they are not 
part of the running system even if disks are mounted there.

Got it, where does it normally live? I apparently have a python-2.6.6 
install.

PCLos is rpm based, lots of mandriva stuff in it.

Path does not exist.  Ends at /usr/share/doc

On PCLos it doesn't even exist in the repo's.

Good links, thank you.

Cheers, Gene
