Please do this.
Download 'Hijack This!'. HijackThis
Save it in a convenient permanent folder such as C:\HJT\, double click HijackThis.exe, and hit "Scan".

Your copy of HijackThis needs to be in a folder of it's own. When HJT fixes anything, it makes backups of the original files in the folder it is in. Since Temporary folders are emptied now and then (the files are DELETED), it would not be a good idea to have your backups there. Those backups would be VITAL to restoring your system if something went wrong in the FIX process!


1. Please go to you're 'My Documents' folder, right-click and select 'New > Folder' then name the folder 'HJT'.

2. Copy and paste HijackThis.exe to the new folder.

3. Close ALL windows except HJT

4. SCAN with HJT

5. POST the new log in this thread using 'Add Reply'

DO NOT MAKE ANY CHANGES OR CLICK "FIX CHECKED" UNTIL WE CHECK THE LOG, AS SOME OF THE FILES ARE LEGIT AND VITAL TO YOUR COMPUTER'S HEALTH

Have Hijack This fix the following by placing a check in the appropriate boxes and selecting fix checked. Make sure all browser and all Windows Explorer windows are closed before fixing.

Or this as a full download without any unzipping required

We have found that some of the CWS infections can be removed better from safe mode, rather than normal mode.
To get to safe mode use the F8 key while booting the machine. Detailed instructions from here :-
