Hey everybody,
I recently (a few days ago) had my homepage hijacked. I fixed it, but it came back the next day and will not go away. It changed my homepage to Home Search, installed the Search Extender (which uses the icon for AOL Instant Messenger), and the Home Search Assistent (the idiot who wrote the hijacker didnt even spell "assistant" right :p ). Here is my logfile of HijackThis. Keep in mind it comes back with a different URL everytime. Any help would be awesome!

Hello please download the latest version of About:Buster and unzip it to your desktop. Donīt run it yet.

How to use Ad-Aware to remove Spyware <= Please check this link for instructions on how to download, install and then use adaware. Donīt use it yet.
1 You already have Adaware installed. Make sure it's up to date. Just open Adaware and click on *Check for Updates Now* and then *Connect*. It will find a new reference-file. Click *ok* and let it download and install the updates by clicking on *Finish* .This will return you to the main screen. You should now see Reference File # : 01R333 18.07.2004 or higher listed.

2 Print out these instructions so you have them handy as most of the steps need to be done in safe mode and you may not be able to go online.

3. Next, go to Start->Run and type "Services.msc" (without quotes) then hit Ok
Scroll down and find the service called "Network Security Service". When you find it, double-click on it. In the next window that opens, click the Stop button, then click on properties and under the General Tab, change the Startup Type to Disabled. Now hit Apply and then Ok and close any open windows. This service is installed by the malware. If this service is not listed go ahead with the next step.

4. Reboot to Safe Mode

5. Make sure your PC is configured to show hidden files

Open Windows Explorer & Go to Tools > Folder Options. Click on the View tab and make sure that "Show hidden files and folders" is checked.
Also uncheck "Hide protected operating system files" and untick "hide extensions for known file types" . Now click "Apply to all folders"
Click "Apply" then "OK"

6.CLOSE ALL WINDOWS AND BROWSERS Scan with Hijack This and put checks next to all the following, then click "Fix Checked"

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = res://C:\WINDOWS\wyxgf.dll/sp.html#26512

R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = res://C:\WINDOWS\wyxgf.dll/sp.html#26512

O4 - HKLM\..\Run: [javajy.exe] C:\WINDOWS\javajy.exe



7. Delete the following files and folders if present.
C:\WINDOWS\system32\iemu32.exe
C:\WINDOWS\wyxgf.dll
C:\WINDOWS\ntes.dll
C:\WINDOWS\javajy.exe


8. Double click AboutBuster.exe that you downloaded earlier. Click OK, click Start, then click OK. This will scan your computer for the bad files and delete them. Save the report(copy and paste into notepad or wordpad and save as a .txt file) and post a copy back here when you are done with all the steps.

9. Scan with Adaware and let it remove any bad files found.

10. Clean out temporary and TIF files. Go to Start > Run and type in the box: cleanmgr. Let it scan your system for files to remove. Make sure these 3 are checked and then press *ok* to remove:

Temporary Files
Temporary Internet Files
Recycle Bin


11. Reboot to normal mode, scan again with Hijack This and post a new log here.

12. Finally, do an online scan HERE. Let it remove any infected files found.

Replace Deleted Files
It is also possible that the infection may have deleted up to three files from your system. If these files are present, to be safe I suggest you overwrite them with a new copy.

Go here: http://www.spywarein...es.html#control and download the version of control.exe for your operating system. If you are running Windows 2000, copy it to c:\winnt\system32\. For Windows XP, copy it to c:\windows\system32\.

Download the Hoster from here: http://members.aol.c...dbee/hoster.zip
Press 'Restore Original Hosts' and press 'OK'
Exit Program.

If you have Spybot S&D installed you may also need to replace one file.
Go here: http://www.spywarein...s.html#sdhelper and download SDHelper.dll. Copy the file to the folder containing you Spybot S&D program (normally C:\Program Files\Spybot - Search & Destroy)

Additionally, Please check your ActiveX security settings. They may have been changed by this CWS variant to allow ALL ActiveX!! If they have been changed, reset your active x security settings in IE as recommended.

Here are some tips, to reduce the potential for spyware infection in the future, I strongly recommend installing the following applications:
  • Spywareblaster <= SpywareBlaster will prevent spyware from being installed.
  • Spywareguard <= SpywareGuard offers realtime protection from spyware installation attempts.
  • How to use Ad-Aware to remove Spyware <= If you suspect that you have spyware installed on your computer, here are instructions on how to download, install and then use Ad-Aware.
  • How to use Spybot to remove Spyware <= If you suspect that you have spyware installed on your computer, here are instructions on how to download, install and then use Spybot. Similar to Ad-Aware, I strongly recommend both to catch most spyware.
To protect yourself further:
  • IE/Spyad <= IE/Spyad places over 4000 websites and domains in the IE Restricted list which will severely impair attempts to infect your system. It basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.
  • MVPS Hosts file <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your coputer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
  • Google Toolbar <= Get the free google toolbar to help stop pop up windows.
I also suggest that you delete any files from "temp", "tmp" folders. In Internet Explorer, click on "Tools" => "Internet Options" => "Delete Files" and select the box that says "Delete All Offline Content" and click on "OK" twice. Also, empty the recycle bin by right clicking on it and selecting "Empty Recycle Bin". These steps should be done on a regular basis.

And also see TonyKlein's good advice
So how did I get infected in the first place?

Good luck :D
