PC Hell: How to Remove WinTools (Huntbar variant):
http://www.pchell.com/support/wintools.shtml

My Basic Instructions -

Restart in Safe Mode:
-Start the computer and hold down the CTRL key till the Windows 98 Startup menu
(boot menu) appears.
-Use the arrow keys to select "Safe Mode" and press Enter.

Click Start> Settings> Folder Options> View tab, and click to enable "Show All
Files" and click OK.

Press Ctrl+Alt+Delete, and End Task on these processes, if they appear:
WToolsA.exe
Wsup.exe

Then delete the Wintools folder, run Hijack This in Safe Mode, and use it to remove
these entries:

R3 - URLSearchHook: (no name) -
{87766247-311C-43B4-8499-3D5FEC94A183} -C:\PROGRA~1\COMMON~1\WinTools\WToolsB.dll
O2 - BHO: (no name) - {87766247-311C-43B4-8499-3D5FEC94A183} -
C:\PROGRA~1\COMMON~1\WinTools\WToolsB.dll
O4 - HKLM\..\Run: [WinTools] C:\Program Files\Common Files\WinTools\WToolsA.exe

Here is my standard response on how to download and use Hijack This:

Download, unzip, and run Hijack This from one of these locations:
http://computercops.biz/downloads-cat-14.html
http://www.majorgeeks.com/downloads31.html
http://www.spywareinfo.com/downloads/tools/HijackThis.exe
Unzip to a folder other than your Desktop or the Temp folder,  doubleclick
HijackThis.exe, and hit "Scan".

When the scan is finished,  the  "Scan"  button will change into a "Save Log"
button.
Press that,  save the log somewhere you can find it (Desktop, My Documents, or
similar).
Most of what it lists will be harmless or even required, so do NOT fix anything yet.

Copy the log files and paste them into a new post at this forum:
http://forum.aumha.org/viewforum.php?f=30

In your post, please state your problem clearly and what you've done so far to fix
it.

See the "housekeeping" you should complete before you post your log:

The folks there will tell you what to remove.
