Norton 2003 running on my XP machine says I have the Trojan Horse virus IETLBASS.DLL. Norton and Ad Aware can't fix it. It keeps coming back. Can anyone help? Thank you in advance. Here's my Hijack this Log:

In addition this entry needs to be fixed. It is a part of the infection:
O4 - Global Startup: RealAudio.exe
If you cannot fix it in regualr mode then boot to Safe mode and do it there.
After you finish, restart, run Hijackthis again and post the new log.

Thanks for the fast reply.

I ran HJT from safe mode
I checked and fixed the following:

O4 - Global Startup: RealAudio.exe

After a normal startup Norton 2003 doesn't report that it found the Trojan Horse virus IETLBASS.DLL.

Here's the new HJT log:

I would also do regular scans using Ad-Aware and Spybot S&D.

If you don't have them, then do the following.

Download Ad-Aware SE from here:
http://www.download.com/3000-2144-10045910.html?part=69274&subj=dlpage&tag=button

Install and run Ad-Aware SE. On the bottom right corner of Ad-Aware you will see an option called "Check for updates now", click on that and choose "connect". Download the updates. Next click on "Scan now" on the left side of Ad-Aware. Make sure that "Search for negligible risk entries" is crossed out and not ticked. Choose "Perform full system scan" and click "Next". After Ad-Aware scans your computer, Ad-Aware may find some bad files on your computer so make sure you tick them all and choose "Next". It will ask if you want to remove those items so just continue. After removing the items close Ad-Aware.

Download Spybot S&D from here:
http://users.skynet.be/fa936042/spybotsd13.exe

Install and run Spybot S&D. Choose "Search for updates". Next choose "Download updates". After that, choose "Search and Destroy" and click on "Check for problems". If Spybot finds any nasties on your computer, make sure that they are ticked and choose "Fix selected problems".

I would also recommend installing SpywareBlaster.

Download SpywareBlaster from here:
http://www.majorgeeks.com/downloadget.php?id=2859&file=11&evp=61b0e8ad41924a03c37615f4682b4cef

Install and run SpywareBlaster. Click on "Updates" and then choose "Check for updates". Next choose "Protection" and at the top you will see different tabs which are Internet Explorer, Restricted sites and Mozilla/Firefox. Choose one of them at a time and at the bottom click "Protect Against Checked Items" (make sure that all of the items are checked). Tick the boxes above the items. Make sure you do this for all of the top tabs. Mozilla/Firefox you only need to do if you have the user profiles on your computer. You may now exit out of SpywareBlaster.
