i reinstalled xp on a computer (new install).
when i use windows explorer to look at another computer (locally), i see something being transfered from the other computer to the new one. (have networx installed on both systems.)
networx show something transfered at 1.0 meg for about 30 seconds.
that is not normal.

so, is there something that will capture that file to have it removed.

comodo is installed on both systems.
