DNS error when I try to visit a antivirus site - Not Hosts file

I'm having trouble reaching any antivirus sites eg Symantec, trendmicro, ca  etc. When I do a ping the address always comes back with 127.0.0.1 - Simple I thought - Hosts file, However the hosts file is as it should be, empty!!

I can add the IP address to the hosts file and then I have no problem reaching the site.

I removed a whole host of virus's from this PC, But It seems there may be an undetected virus remaining, or registry entries preventing the install of antivirus software, It also prevents te windows installer service from working - so I can't run trends housecall.

I would really appreciate some help here - the PC's not mine - so I can't throw it out the window !!!

Hello chrisdotc =)

First Run Stinger in Safemode ==> http://vil.nai.com/vil/stinger

If ti comes as clean, then Can u Download HijackThis v1.98.2 from here, run it and Save the LOG file:
http://tools.radiosplace.com/HijackThis.exe

Then Post it at this site >> http://www.hijackthis.de/index.php?langselect=english
and it will automatically analyse it for u,,, Fix everything which it asks u to delete :)

and if still u cannot get it working, then Post here that LOG file, and we will tell u that what is BAD in it and how to remove them :)

!! GOOD LUCK !!

Hi SheharyaarSaahil

Thanks very much for your quick response all problems now solved - Ran Stinger forund Qhosts.apd Trojan in Windows\system32\drivers\etc\Hosts !!

Don't understand that - File seemed normal I even added entries to it.

All AV vendor sites were available after that, But installer still didn't work.

Ran Hijack This and got a quick analysis as sugested - Fixed the the errant entries rebooted and Now Norton AV is installing.

I will post the Hijack This Log for the benefit of others if it you think it is appropriate.

Thanks again for your Help

Well if the problem is solved and everything is running OK, and even Stinger is not reporting Qhosts.apd trojan, then there is not need to post the LOG file,,,, coz it will be not beneficial for other users... two logs from two different systesm cannot be treated with one solution :)

Post back if u have any more question or problem =)
