Run Hijack This again and put a check by these. Close ALL windows except HijackThis and click "Fix checked"

Restart in Safe Mode:
Restart your computer.
Press F8 after the Power-On Self Test (POST) is done. If the Windows Advanced Options Menu does not appear, try restarting and then pressing F8 several times after the POST screen.
Choose the Safe Mode option from the Windows Advanced Options Menu then press Enter.
Because XP will not always show you hidden files and folders by default, Go to Start > Search and under "More advanced search options".
Make sure there is a check by "Search System Folders" and "Search hidden files and folders" and "Search system subfolders"
Next click on My Computer. 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 "Hide extensions for known file types" . Now click "Apply to all folders"
Click "Apply" then "OK"
C:\Program Files\Common Files\WinTools <-- Delete wintools from Add/Remove programs
C:\WINDOWS\system32\spoolsvc.exe <--Delete File
C:\WINDOWS\system32\wpabaln.exe <--Delete File
Also in safe mode navigate to the C:\Windows\Temp folder. Open the Temp folder and go to Edit > Select All then Edit > Delete to delete the entire contents of the Temp folder.
Next navigate to the C:\Documents and Settings\(EVERY USER)\Local Settings\Temp folder. Open the Temp folder and go to Edit > Select All then Edit > Delete to delete the entire contents of the Temp folder.
Finally go to Control Panel > Internet Options. On the General tab under "Temporary Internet Files" Click "Delete Files". Put a check by "Delete Offline Content" and click OK. Click on the Programs tab then click the "Reset Web Settings" button. Click Apply then OK.
Empty the Recycle Bin

On the Desktop, right-click My Computer.
