Here is what I found after spending some time with an infected machine. In
C:\Winnt\System32 there are two files, winampa.exe and winampa.exe.poly
which are both 226K. There is also a service installed called Win leoahder.
In the registry in HKLM\Software\Microsoft\Windows\Current Version\Run and
Run Services there is a key named win leoahder. I deleted the two registry
keys and the two files and I was able run regedit as well Norton. Not sure
if this was a virus a worm or some spyware.

Sounds like it could be the 'exploit' for the ASN.1 vulnerability
(MS04-007) in Windows which was released and is apparently being
actively exploited on the Internet.
