The above link contains the following instructions...
1) With “Reglite.exe” find name of hidden file:
Double Click on “AppInit_DLLs” located in “HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWindows” The “value” window reveals the hidden file name. (mine was “hlpl.dll”, yours may be different!) In this example let’s call it “hidden.dll”
2) Rename the hidden file:
Close Windows and reboot using “Windows Recovery Console” Go to “c:Windowssystem32” and do two things. Change file from read only by typing “attrib –r hidden.dll” Then rename it (I don’t know why, but this procedure did not work until I renamed it) type “rename hidden.dll nasty.dll” (and remember that “hidden.dll” is for this explanation only use the name you found earlier) Type “exit” and reboot to Windows.
3) Edit registry to remove hidden file
Run “reglite.exe” again. Double Click on “AppInit_DLLs” located in “HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWindows” Delete the file in “value” window, the “size” window changes also. “Apply” changes and exit “reglite.exe”
4) Edit registry to remove the second file
Run “HiJackThis.exe” and scan the registry. Check the boxes to remove the following entries:
“R1 - HKCUSoftwareMicrosoftInternet ExplorerMain,Search Bar = res://C:WINDOWSSystem32jheckb.dll/sp.html (obfuscated)
R1 - HKCUSoftwareMicrosoftInternet ExplorerMain,Search Page = res://C:WINDOWSSystem32jheckb.dll/sp.html (obfuscated)
R1 - HKCUSoftwareMicrosoftInternet ExplorerSearch,SearchAssistant = res://C:WINDOWSSystem32jheckb.dll/sp.html (obfuscated)
R1 - HKLMSoftwareMicrosoftInternet ExplorerMain,Search Bar = res://C:WINDOWSSystem32jheckb.dll/sp.html (obfuscated)
R1 - HKLMSoftwareMicrosoftInternet ExplorerMain,Search Page = res://C:WINDOWSSystem32jheckb.dll/sp.html (obfuscated)
R0 - HKLMSoftwareMicrosoftInternet ExplorerSearch,SearchAssistant = res://C:WINDOWSSystem32jheckb.dll/sp.html (obfuscated)
R1 - HKCUSoftwareMicrosoftInternet ExplorerMain,HomeOldSP = about:blank” (as you can see my second .dll was called “jheckb.dll” yours may be different) For this example let’s call it “obvious.dll”.
Finally delete the two .dlls (“hidden.dll” and “obvious.dll”) You should be running again.
By the way, if you go offline with Internet Explorer and type OK To these nasty adware windows you will see the guys who benefit. From this hijacker. I found:
www.palsol.com
www.likesurfing.com
www.vn.msie.cc (the real web page)
They seem to be selling “adware/spyware protection” Pass the word, Boycott them, Who needs to be extorted for “protection money”?
I wouldn't suggest messing around in the registry file unless you know what you are doing. The slightest typo will possibly render your system unbootable.
