hello all i got the answer for this its due to Qhosts-1
trojan
MS0-032 patch is a cure for it.

thanks again
 
It's a new virus, dubbed "Trojan.Qhosts".

Discussed here:
CERT:
http://www.cert.org/incident_notes/IN-2003-04.html
Symantec:
http://securityresponse.symantec.com/avcenter/venc/data/trojan.qhosts.html
Network Associates:
http://vil.nai.com/vil/content/v_100719.htm

It infects your system, changes your DNS.

It's because of a Windows IE problem whereby clever code in a webpage
can trigger a problem with the Microsoft Html application handler and
execute code on your comptuer.

Symantec has as of yet no fix in norton antivirus for it. I
downloaded the "Live update" for 10/1/2003, and it didn't find it. I
then downloaded the "intelligent update"
(http://securityresponse.symantec.com/avcenter/download/pages/US-SAVCE.html)
which you have to do manually, and so far, the scan has found nothing.
Luckilly, the page on symantec's response says that a fix will be
comming out in next week's live update.
