0.0.0.0 is blocking connections?!

for a few days now i have been having trouble accessing sites. this is weird, because i can access certain sites but as i am surfing one site will stop working, but others will carry on. i tried powering down my modem for 60 secs and then doing it again, sometimes that works.
anyway, i have a broadband modem/router, at its default lan address.
so i try a trace route program to see if there is a server down. it is being a little slow, but... most hops get 100% loss at IP address 0.0.0.0! my computer! i have windows firewall turned off, in fact i have no firewall (lol not sure i should be posting this)
sometimes, although there is apparently 100% loss, somehow the trace route carries on. but on certain sites it just refuses to budge.

very confusing....https://forums.windrivers.com/images.../2005/02/1.gif

Hmm, if you've been running XP with no firewall, I'd think your system has almost certainly been compromised...

Some nasties will fiddle with your HOSTS file, check & see if your commonly accessed sites have been redirected there to 0.0.0.0

What security provisions do you have set up apart from being non-firewalled?

First suggestion is always comprehensive virus, trojan & malware scans, & have all security patches up-to-date.

Your host file can be found here:

x:\WINNT\system32\drivers\etc\hosts

(Where "x:\" = the drive windows is installed on.)

If you have an OEM version of Windows XP, you'll find it here:

x:\windows\system32\drivers\etc\hosts

You can open\edit the file using notepad.exe or other text editing program.
