Hello Cerenia and welcome to Bleeping Computer,

Please read [url="http://"http://www.bleepingcomputer.com/combofix/how-to-use-combofix"]this tutorial[/url] carefully to download ComboFix from one of the locations specified, and save it to your Desktop.
Double click the ComboFix icon to run it.
If ComboFix askes you to install the Recovery Console, please do so..
The Windows Recovery Console will allow you to boot up into a special recovery mode, in case your computer has a problem after an attempted removal of malware. This allows us to help you.
Once the Recovery Console is installed, continue with the malware scan.

Note: Make sure not to click ComboFix's window while it's running. That may cause it to stall or freeze.

Please post the log from ComboFix (can also be found as C:\ComboFix.txt) in your next reply. :thumbsup:

If you have any questions along the way, STOP and ask them before proceeding !!

Greetings,
Thunder

Excellent, Cerenia :thumbsup:

You can remove all used tools and folders created in the process.
To remove ComboFix :
Go to Start > Run, and copy and paste next command in the field:ComboFix /u
Make sure there's a space between Combofix and /u
Then press Enter.
This will uninstall Combofix, delete its related folders and files, restore your clock settings, hide file extensions, hide the system/hidden files and resets System Restore again.

Please read this Prevention page with lots of info and tips how to prevent this in the future.
And if you want to improve speed/system performance after malware removal, take a look here.
Extra note: Make sure your programs are up to date - because older versions may contain Security Leaks.
To find out what programs need to be updated, please run the Secunia Software Inspector Scan.

Please also read Tony Klein's excellent article: How I got Infected in the First Place
and/or Grinlers tutorial on how malware is hidden and installed

Since this issue appears resolved ... this Topic is closed.
If you need this topic reopened for continuations of existing problems, please request this by sending me a PM with the address of the thread. This applies only to the original topic starter.

Everyone else please begin a New Topic.
