Was running my Spybot tonight and My Norton Anti-Virus popped a warning message that I had a Trojan Horse and that it is unable to repair the file.
The location is C:WINNT/Launchurl.exe.

I could not remove the file manually.

Can you help?

Let us take a closer look at what is running on your PC. We'll need you to use a free diagnostic tool (HiJackThis) and post a log back here with the results.

Click the HijackThis Guide in my signature, download it and follow the instructions in the guide.

Most of what it lists will be harmless or even essential, DO NOT delete or modify anything yet! Someone will be along to tell you what steps to take after you post the contents of the scan results.

Here is the log....Had to reboot as i wanted to load the TDS 3 trojan detector. Have not run it. Because I had a copy of a clean hijack log from before I see a suspecious entry:

O1 - Hosts: 64.91.255.87 www.dcsresearch.com

Which was not there prior to reboot.

My LIVE Update is automatic but did it anyway and rebooted...Thats where i saw the HOST entry in previous message.

I re-ran the scan of the Winnt Directory and Norton this time, did not detect the Virus...Does it 'go away' after making that host entry?? Will rerun spybot and adaware as i await ur reply.

Great job. Congratulations! Your system is CLEAN :tazz:

How do you prevent spyware from being installed again? We strongly recommend installing SpywareBlaster (it's free for personal use) Click Here.

Prevent the installation of ActiveX-based spyware, adware, browser hijackers, dialers, and other potentially unwanted pests.
Block spyware/tracking cookies in Internet Explorer and Mozilla/Firefox.
Restrict the actions of potentially dangerous sites in Internet Explorer.
Consumes no system resources.

Download, run, check for updates, download updates, select all, protect against checked. All done. Check for updates every couple of weeks. If you have any errors running the program like a missing file see the link at the bottom of the javacool page.

It's also very important to keep your system up to date to avoid unnecessary security risks. Click Here to make sure that you have the latest patches for Windows.

These next two steps are optional, but will provide the greatest protection.
1. Use ANY browser besides Internet Explorer, almost every exploit is crafted to take advantage of an IE weakness. We usually recommend FireFox Posted Image.
2. Install Sun's Java. It's much more secure than Microsoft's Java Virtual Machine .

It's okay to delete the Hijack This folder if everything is working okay.

After doing all these, your system will be thoroughly protected from future threats. ;)
