Hi jjs,

Net.exe could be a process that comes with malware known as w32.dabber.c worm.
This might have come together with an e-mail message you opened recently.
See description here: http://www.liutilities.com/products/wintaskspro/processlibrary/net/
If this scenario rings some bells and the proposed scan by Pondus does not show you that you have the legit net.exe,
indeed go here: http://forum.avast.com/index.php?topic=53253.0
Provide the logs asked for there and a qualified removal expert will have a look
and help you with the cleansing the malcode from your machine,
