Then using Windows Explorer, delete the following folder: C:\Program Files\AlfaCleaner

Download HijackThis and save the file to your desktop.
Double click on the file to extract it to it’s own folder on the desktop.

If you do not already have Ad-Aware SE installed, follow these download and setup instructions. Also check for updates.

Again, do NOT run a scan yet.

Next, please reboot your computer in Safe Mode by doing the following:

1. Restart your computer
2. After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
3. Instead of Windows loading as normal, a menu should appear
4. Select the first option, to run Windows in Safe Mode.

Now you need to run HijackThis and click “Do a system scan only.” Place a check next to the following entries (if they are still there):

O4 - HKLM\..\Run: [AlfaCleaner] C:\Programas\AlfaCleaner\AlfaCleaner.exe

Now close all browser and other windows except for HijackThis, and click “Fix Checked” to have HijackThis fix the entries you checked.

Next, run Ad-aware and perform a full scan. Remove everything found.

Finally, restart your computer normally.
