I HAVE THE SAME PROBLEMS AS REPORTED ABOVE

THANKS FOR PORT 25 INFO

This worked for me at first, I went into my linksys
router and blocked all ports 0-26, my internet
connection immediately improved, this worked
at first, but shortly after the connection
is still bad but it is better than before.

This thing is also screwing up my other programs.
Everything is slower but not as noticeable
as really bad internet connection.

AVG does not pick this up.
Spybot kills files but cannot get the source.
