Welcome to TSF.
Before you do anything else, please create a folder for HijackThis and put it in a permanent folder (like C:\HJT) instead of the Temp folder. This is required because HijackThis will create backups and we don't want them to be deleted.
Please print out or copy this page to Notepad. Make sure to work through the fixes in the exact order it is mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. You should
not have any open browsers when you are following the procedures below.
Make sure to close any open browsers. Run a scan in HijackThis. Check each of the following and hit 'Fix checked' (after checking them) if they still exist (make sure not to miss any):
O16 - DPF: {05D96F71-87C6-11D3-9BE4-00902742D6E0} (QuickPlace Class) - https://quickplace1.emea.gweb.eds.com/qp2.cab
Go to Start->Run and type in regedit and hit OK. Go to File->Export and save the registry somewhere as a backup. While in the Registry Editor, navigate to:
HKLM\SYSTEM\CurrentControlSet\Enum\Root\ and delete
LEGACY_DELPROT
If any of the above registry keys are giving you problems deleting, right click on them and click on Permissions. Then click on the Advanced button. Make sure the first box (Inherit from parent...) is checked. Click OK and OK. Then try deleting the entry again. Once you're done, close the Registry Editor.
Restart. Any problems now?
