Hi - I'm helping out my next door neighbors. They have a Windows 2000 SP4 system with IE6, not up-to-date with the latest service packs. They have Ad-Adaware and have run it already, and they have Norton anti-virus 2003.

They cannot access the internet and the 404ads.net redirect keeps happening. I'm trying to help them out, so I've run HijackThis 1.98.2 on their system and retrieved the following logs. Any help would be appreciated.

Please Download LSPFix from http://www.cexx.org/lspfix.htm and Run the Program. Disconnect from the Internet and close all Internet Explorer Windows. Check the "I know what I'm doing" Button and remove all traces of lsp.dll. Reboot.

You have a number of randomonly named files on your system. We like to start with an online virus and trojan scan. Even though you have antivirus software on your system, it can become corrupted by malware.

Please run a free online virus scan here (tick the "Auto Clean" checkbox):
http://housecall.antivirus.com/

And a free trojan scan here:
http://www.moosoft.com/

Download Ad-aware from: http://www.geekstogo...n=download&id=5

Install the program and launch it.

First, in the main window, look in the bottom right corner and click on Check for updates now and download the latest reference files.

Next, we need to configure Ad-aware for a full scan.

-> Click on the Gear icon (second from the left) to access the preferences/settings window

1. In the General window make sure the following are selected:
  • Automatically save log-file
  • Automatically quarantine objects prior to removal
  • Safe Mode (always request confirmation)
2. Click on the Scanning button on the left and select :
  • Scan Within Archives
  • Scan Active Processes
  • Scan Registry
  • Deep Scan Registry
  • Scan my IE favorites for banned URL’s
  • Scan my Hosts file
  • Under Click here to select drives + folders, choose:
  • All of your hard drives
-> Click on the Advanced button on the left and select:
  • Include additional process information
  • Include additional file information
  • Include environment information
  • Include additional object details
-> Click the Tweak button and select:
  • Under the Scanning Engine:
    • Unload recognized processes during scanning
    • Include basic Ad-aware settings in logfile
    • Include additional Ad-aware settings in logfile
  • Under the Cleaning Engine:
    • Let Windows remove files in use at next reboot
-> Click on Proceed to save the settings.

-> Click Start and on the next screen choose Activate in-depth Scan at the bottom of the page and then choose:
  • Use Custom Scanning Options
-> Click Next and Ad-aware will scan your hard drive(s) with the options you have selected.

-> Save the log file when it asks and then click Finish

-> When finished, mark everything for removal and get rid of it. (Right-click the window and choose Select All from the drop down menu and click Next).

Please delete your temporary files by deleting all files and folders that are in those folders (do not delete the temp folder itself) like for example
C:\WINDOWS\Temp\
C:\Temp\
C:\Documents and Settings\username\Local Settings\Temp\
Also delete your Temporary Internet Files, be sure to also select delete all offline content.

-> Reboot your computer.

If you would please, rescan with HijackThis and post a fresh log in this same topic.

Did they buy the computer from a business. It is locked down for some reason.

See below:

Registry Key: HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System
Example Listing O7 - HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System: DisableRegedit=1

Please note that many Administrators at offices lock this down on purpose so having HijackThis fix this may be a breach of corporate policy. If you are the Administrator and it has been enabled without your permission, then have HijackThis fix it.

I need to know if it is a business computer before I provide a fix.

I installed the LSP fix, which worked and then I ran all the scans and tools. It got rid of about 10 Trojans and 860 objects using Ad-Aware. I also purged all Temp files.

Here's the latest HJT Log

thanks a ton for the help.

860 objects using Ad-Aware

:P That's a lot! Looks like you get 'em all. <_<

Just a little house cleaning. Please go offline, close all browsers and any open Windows, making sure that only HijackThis is open. Scan and when it finishes, put an X in the boxes, only next to these following items, then click fix checked.

Congratulations! Your system is CLEAN :D

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. :D
