Extract the content (a folder named SmitfraudFix) to your Desktop.
Next, please reboot your computer in Safe Mode by rebooting the computer,
and repeatedly tapping the F8 key as the pc starts. Choose "Safe Mode" from
the options listed.
Once in Safe Mode, open the SmitfraudFix folder again and double-click
smitfraudfix.cmd
Select option #2 - Clean by typing 2 and press "Enter" to delete infected
files.
You will be prompted : "Registry cleaning - Do you want to clean the
registry?" answer "Yes" by typing Y and press "Enter" in order to remove
the Desktop background and clean registry keys associated with the

The tool will now check if wininet.dll is infected. You may be prompted to
replace the infected file (if found); answer "Yes" by typing Y and press

The tool may need to restart your computer to finish the cleaning process;
if it doesn't, please restart it into Normal Windows.
The report can also be found at the root of the system drive, usually at C:\rapport.txt
