Hi,

Let's do this first:

Please download Unhide by Grinler from here

Save it to your desktop and double click Unhide.exe to run it

Has that resolved the hidden files issue?

Download Combofix from any of the links below, and save it to your desktop.

When saving ComboFix rename it to Crush.exe to prevent it from being blocked by malware.

As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. This will not occur in Windows Vista and 7

It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.

If you did not have it installed, you will see the prompt below. Choose YES.

Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Click on Yes, to continue scanning for malware.

When finished, it will produce a report for you. Please post the contents of the log (C:\ComboFix.txt).

Leave your computer alone while ComboFix is running. ComboFix will restart your computer if malware is found; allow it to do so.

Note: Please Do NOT mouseclick combofix's window while its running because it may call it to stall.
