Tracking cookie/spyware/adware/malware?
Hi, I was recently interested to see if there were any tracking cookies or malware or the like on my macbook pro (using safari). I went to a thread here:
Mac spyware/adware/malware problem - MacRumors Forums

where people suggested
% cat /private/etc/hosts
or equivalently
% cat /etc/hosts
...but did not suggest any followup courses of action in case there was a problem.

when I did this I saw an unusual entry (at the end) that I don't quite understand:


$ cat /etc/hosts

# Host Database
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##        localhost        broadcasthost
::1            localhost
fe80::1%lo0        localhost

is there a problem with that last entry? It looks odd to me. If not, what is it? If so, what should I do?

Is there another (easier?) way to determine if I have any tracking cookies or malware installed on my computer? My specific question actually arises from this general question.

Thanks for that quick reply which answers my general question. I hope that I also might get an answer to my specific question above as well. :)

Google is your friend. Here is the answer to your question.

:Oops: :Blushing: ohhh that hurts... Sorry didn't I search that. I thought, naively, that that strange IP would certainly be specific to my machine.
Thanks many times,
