cannot find serveror dns error/page cannot be displayed

[dee mattice]

i'm having trouble getting onto websites all of a sudden.
i didn't have problems before. i've now struggled finding
how to fix the problem for a week. i can get onto search
engines, but some of the pages will not display. yahoo
search won't diplay results, yet i can get onto any of
their page links. search a lot will give me displays, but
not every page is available to me. i can go to any of my
favorites links. does anyone have any idea what's going
on? the program i have is windows ex for the home 2002.

Hi,

It sounds like you've been infected with the Trojan.Qhost bug.
The new Qhosts bug exploits the unpatched residual vulnerability in
MS03-032.

Information regarding this can be found here.
http://vil.nai.com/vil/content/v_100719.htm and
http://securityresponse.symantec.com/avcenter/venc/data/trojan.qhosts.html

The removal tool for this trojan is available here:
http://securityresponse.symantec.com/avcenter/venc/data/trojan.qhosts.removal.tool.html

The bug sets all search values to google. You may wish to change your
configuration on your Internet
Explorer search settings as desired, if you don't want google.

To prevent this exploit, install the critical update described by
bulletin MS03-040 and KB828750. To test your browser vulnerability to
this exploit, see http://www.secunia.com/MS03-032/.
