Working with system restore

****************************************************************************

Just to make sure we got all of the CWS infection, please do the following:
1. Download DLLFix from one of the following links. Save it to a folder on your root drive, which is C:\ for most people:

http://downloads.subratam.org/dllfix.exe

or

http://tools.zerosrealm.com/dllfix.exe

Step 2. After it has completed downloading, navigate to the folder you saved it in and double-click on dllfix.exe.

Step 3. It will prompt you to extract the files somewhere. Type in c:\dllfix and press install.

Step 4. Navigate to c:\dllfix, open the folder and double-click on start.bat

Step 5. Run Option 1 by pressing 1 on the keyboard. The program will now start searching.

Step 6. Once the search is complete a text file should open with the name Output.txt. Copy and Paste the contents of this text file to your next reply to this post.
There are a few variants of CWS that are a ba***rd to remove.
