Windows XP Tips, Illustrations and registry edits
|If you see a Search Assistant Toolbar in the Taskbar, it might be due to a malware named BlazeFind. Quick Launch bar may be missing on every reboot or the Quick Launch sort order may not be maintained.|
These symptoms are caused by this Malware. This page discusses the preliminary steps required to remove this Desk band object, before running spyware removal tools.
Phase I - Removing the Search Assistant Toolbar from the Taskbar
Click Start, Run and type this command exactly as given and press Enter:
regsvr32 /u "%Systemroot%\System32\omniband.dll"
This uninstalls the Search Assistant Desk Band settings in the registry. Next, rename the file omniband.dll to old_omniband.dll and reboot Windows.
Phase II - Fixing a registry entry which causes the Quick Launch issue (not retaining the settings)
Click Start, Run and type REGEDIT. Navigate to:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ WindowsNT \ CurrentVersion \ Winlogon
In the right-pane, change the value of Userinit to
Type the above value exactly as given, including the comma - exclude the quotes. Also, change the path to userinit.exe appropriately if Windows is installed in a different drive.
Close Registry Editor and restart Windows. The Quick Launch settings should be retained now.
Phase III - Removing the Malware from the system
Follow the advice here and run all the tools documented in this page. Be sure to update them before scanning!
Unable to logon to Windows after removing BlazeFind using a spyware removal utility?
Logon - Logoff loop, also caused by BlazeFind
Another critical symptom caused by this malware: This malware modifies the Userinit area in the registry (replacing the userinit.exe with wsaupdater.exe) and Ad-Aware (with a particular definition update) removes the wsaupdater.exe file from the system, thus causing the Logon - Logoff loop. That is, when you login to Windows, the 'loading personal settings" verbose will appear, but suddenly it will logoff. This issue was documented clearly by Lavasoftusa in it's Lavahelp Knowledgebase.
Here is the solution to the logon - logoff issue in Windows XP.
Enter the Recovery Console
Boot the system using the Windows XP CD-ROM. In the first screen when the Setup begins, read the instructions press "R" (in the first screen) enter the Recovery Console. Type-in the built-in Administrator password to enter the Console. You'll see the prompt reading C:\Windows (Or any other drive-letter where you've installed XP)
Type the following command and press Enter.
(If that does not work, try CHDIR SYSTEM32)
COPY USERINIT.EXE WSAUPDATER.EXE
Quit Recovery Console by typing EXIT and restart Windows.
You'll be able to login successfully as you've created the wsaupdater.exe file (now, a copy of userinit.exe)
Now, change the USERINIT value in the registry (see Phase II in this page) and change it accordingly.
