Hi,
Download Webroot Spysweeper Trial and install it.
Next, download CWShredder . Do not run both of these now.
Reboot in Safe Mode:-
Restart (or switch ON) the PC.
Then, keep tapping the F8 Key.
From the menu that will be displayed, out of which choose Safe Mode and press Enter.
Run WebRoot SpySweeper, Click "Options" button and click "Sweep Options" tab, and here select all the Hard Disk Partitions. In the "Where to sweep" option box, select "Sweep all folders on the selected drives". In the "What to sweep" option box, make sure all the items are selected. Then click "Sweep Now" button and click "Start" and remove anything it may find.
Next, run CWShredder and click "Fix->" button.
Reboot the PC to Normal Mode. Download L2mfix from one of these two locations:
http://www.atribune.org/downloads/l2mfix.exe
http://www.downloads.subratam.org/l2mfix.exe
Save the file to your desktop and double click l2mfix.exe. Click the Install button to extract the files and follow the prompts, then open the newly added l2mfix folder on your desktop. Double click l2mfix.bat and select option #1 for Run Find Log by typing 1 and then pressing enter. This will scan your computer and it may appear nothing is happening, then, after a minute or 2, notepad will open with a log. Copy the contents of that log and paste it into this thread along with a fresh HijackThis log.
IMPORTANT: Do NOT run option #2 OR any other files in the l2mfix folder until you are asked to do so!
