Norton AntiVirus (WinXP) reports worm on Tor

Was running Tor on Windows XP as a server. Was showing very low bit rates -
so decided to upgrade to newest version of Tor when it came out.

Now Norton Anti Virus is popping security alerts "Norton Internet Worm Protection
has detected a remoter system that is trying to access your computer..."
Path C:\Program Files\Tor\tor.exe
Direction: Inbound
Local address (my NATed local IP)
Local Port 19001 (the port I selected for Tor to use)
Remote address 212.x.x.x (someone elses IP)
Remote port 60832

This keeps occuring at irregular intervals, even when I select "Permit" and have
attempted to configure Norton to allow tor.exe.

This did not happen on

Have searched for similar issues experienced by others but no luck - any ideas
(besides not running Tor server on XP)

I found a way to get around this. In Norton AntiVirus (2005), define a new 'permit' rule for Worm protection.

  • Options , Internet Worm Protection, General Rules
    • Permit - Any Computer (TCP, local port 19001 (and move this rule up to before the 'deny' rules

(port 19001 is the port I use for Tor server)

This appears to have done the trick. The thing I don;t understand is why on Tor that this was not a problem.

I think this issue can be closed now - but would recommend adding these details in the documentation for Windows.

We've already got a FAQ entry here:

This happens every few releases for some antivirus program or other.
