FTP no longer works on my mac

My macbook pro is no longer able to ftp. I know its my computer because when I ftp from my iPhone there is no issue. I have tried multiple ftp servers, replaced the router / modem that my isp gave me, and done a factory reset on the modem.

The error results in Coda are: Error -135: socket write error
The error results from Filezilla are: Could not write to socket: EPERM - Permission denied

When I run a traceroute I get a huge delay leaving my internal ip (see the *; took up to 15 seconds to find the next ip):

The only recent update I have done was installing norton antivirus. However, when I turn the firewall completely off it still doesn't work. I have checked with my isp and hosting company and there is no blockage on my ip. This issue has been consistent for 3 days.

Short of a complete reformat, is there a setting I can apply on my modem (hitron from rogers cable), or a setting on my mac I can change?

Try uninstalling Norton completely. That seems to me to be the likely cause.

Hi strung,

Looks like it was norton. Guess something in its config.
First I uninstalled it and booted in safe mode and it worked.
Tried again in normal boot without norton and it worked.
Then I reinstalled it under its original configuration and no problems :)

TYSM for the help strung.
