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/.
