My browser page keeps changing to About:blank. IE search button gets overridden too. Have run CWSshredder, adaware, Hijackthis, Malwhere, PV. Some of these return results with files linked to CoolWebSeach. CWSshredder claims to remove the variant CWS.searchx, but even after that, adaware still finds CWS stuff in the registry, and it re-spawns again after a system resart and a few browser page openings. I would greatly appreciate any help.

Can you please download HijackThis from this link, install it into C:\HJT. Run it, click on scan, save log and please post your entire log here for analysis.

Thank you.

  • Download reglite
  • install "Reglite" and run it, enter HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\ into the address bar.
  • Double click on AppInit_DLLs to open a "Data Editor" properties window, if the bottom textfield named "Value" contains a .dll file; then this is the hidden file you need to get rid off.
  • You should not be able to delete this file if you try to clear the value field, IMPORTANT: take note of the path and name of the .dll file. Write it down so you do not forget it.
  • Rename the Folder "Windows" (This is a purple "highlighted" folder in the left hand window) to NOTWINDOWS. Simply click on the folder, click on "Edit" in the menu bar and select "Rename".
  • Click AppInit_DLLs again and clear the value containing the .dll and ok it. This should have removed the .dll
  • Rename the windows folder back to its original name "Windows".
  • Run SpyBot, Ad-Aware and CWShredder
  • Check the following three links for instructions on downloading and running the applications listed:
  • Next step will be to remove this dll file so make sure you have it noted down.
  • Procedure 1
    • Download KillBox
    • Unzip and start the application
    • Paste in the dir <path and name of dll as found in the appinit value box> e.g. C:\Windows\System32\nameofdll.dll
    • Menu Select Action => Delete on Reboot
    • Select File => Add file <It should add the path automatically>
    • <Same Window> Select Action => Process and Reboot
  • Procedure 2 (If Procedure 1 did not work)
    • Click "Start" => "Run" and type in "cmd" (Without the quotations) and click on "Okay".
    • This will open a command window I will assume you have a basic knowledge of DOS if you have any problems at this point just write back I will outline the commands.
    • Type in dir <path and name of dll as found in the appinit value box> and press "Enter". You should see the name of the file listed.
    • Go to the system32 folder (This is where the .dll file will typically reside) and type attrib -R "nameofdll".dll
    • Carry out Procedure 1 again
  • Restart your computer in safemode (How do I boot into "Safe" mode?)
  • Open cmd window again as before
  • Type dir <path and name of dll as found in the appinit value box> and locate the dll name the dll should now have been removed and will not be listed.
  • While in safe mode, run the 3 ad-removal programs again, just to make sure all traces are gone.
  • Boot up pc as normal and you should be trouble free.
Run HijackThis and delete the following if still present:

Reboot and post a new log for further review.

Check the properties of the file to ensure that your account has access - It may be a simple matter of adding yourself to the security of the file. Also - I am a bit confused on your logs as you are running HijackThis from different locations which would indicate either another user profile or multiple copies of HijackThis. Please be sure only to run it from C:\HJT.
