"Unable to Resolve Host"

I'm at wit's end. I'm certainly not a computer whiz, but
I'm not exactly illiterate either.

I have a Dell Dimension 4500. I have Norton Internet
Security 2004 installed, and Adaware 6.0. I used to have
Spybot, but I recently uninstalled it (thought it may have
been causing my problem).

The problem is every time I try to launch Internet
Explorer, I get the "unable to resolve host
www.yahoo.com" message. I have a DSL cable modem , and
it's working perfectly (I am able to dial into my VPN
connections with no problems). The first time I got this
error, I popped in my ISP's setup CD and reinstalled it,
which worked. Of course, the problem came back and now
reinstalling doesn't fix it. I tried typing in different
web addresses and nothing works.

If looked all over for an answer to this and can't find
anything on this.

Any advice on this would be GREATLY appreciated.


Thank you,
Brian
 
And your ISP is...? (You don't need anything on the Setup CD to use this
ISP, Brian.)

Dealing with Trojans & Hijackware

A. Trojans

1. Check in at Windows Update and install all critical updates & reboot.

2. Download and run Stinger (http://vil.nai.com/vil/stinger/); then...

3. Update your virus definitions, enable Show Hidden Files
(http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2002092715262339)
and then run a full system scan in Safe Mode
(http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406)
with nothing else running in background. Note the files identified and
removed then find the corresponding page for the file at your AV maker's
online support pages (e.g.,
http://securityresponse.symantec.com/avcenter/venc/data/adware.winfavorites.html)
and follow *all* Removal steps, including editing the Registry if directed.

WinXP Only (WinME similar): If this scan finds anything, create a new
Restore Point then:

Disk Cleanup > More options > Delete all but the most recent Restore
Point.

Run these tools in the following order with nothing else running in
background:

1. CWShredder v1.59.1 (no updates available currently; fix all found)

2. Ad-Aware *SE* [replace v6] (reconfigure per Post #2 in
http://aumha.org/forum/viewtopic.php?t=5877; fix all found)

3. Spybot (RTFM but generally fix everything in red)

Important: You must seek updates for Ad-Aware, Spybot, etc., before each and
every use, even "right out of the box". But even they can't catch
everything, 24/7. When all else fails, HijackThis
(http://forum.aumha.org/downloads/hijackthis.zip) is the preferred tool to
use. It will help you to both identify and remove any hijackware/spyware.
