Hi,

Real newbie here so please excuse the dumb questions and comments.

I ran a HighJackThis scan this morning (first in a long time) and noticed these two listings. I do have a wireless card in my PC and I do have a wireless router but both are turned off and secured as far as I am aware. I also run HostMan Hosts files.

O1 - Hosts: ::1 localhost
O1 - Hosts: 255.255.255.255 broadcasthost


No idea what they are and if I need to do anything. Your help would be appreciated.

Regards

laopa :thumbsup:

Hello,

::1 is an IPv6 address that routes back to your own computer. It's the IPv6 version of 127.0.0.1, aka localhost. 255.255.255.255 is different, but it works a similar way. It's a broadcast address that sends information to the zero network (0.0.0.0), which basically means "this network". Both are perfectly harmless.

Cheers,

Hi,

Thanks for the quick feedback. I feel I little safer and better now. Are these two listing related to the HostMan Host File setup and program?

Regards

Hi,

They're likely just installed by default by Windows (possibly an XP thing, as I don't have those in my Vista default hosts file). If not, they'd be the doing of HostMan. They're not dangerous entries, so they wouldn't be caused by an infection.

Hope this helps,

Yep, should all be good. Nothing malicious by the looks of it.

Have a nice day!
