garbanza,

There are 2 ways we can try to fix this:

  1. Reassign new port numbers to Avast and your email client.
  2. Find the program using Port 25 and see if it is essential to have running at startup.

Follow VLK’s advice and look over the TCP report and see if any other instance of STMP is listed.

Then, I would run MSCONFIG and go the Startup tab.
Review the list for any program that you are not familiar with.

Also, what email client do you use?
Is it set to load with Windows?

Although Netstat is useful, it does not give you a clear picture of who is using what.
TCP is nice, but unless you know how to interpret the data, you still don’t know what your looking at.

I had a nice Port scanner program somewhere that I will have to find for you.

Anyway, try the above and let us know.
