System Security Virus - Bad problems after I deleted it!

Click Start > Run and copy/paste the following bolded text into the Run box and click OK:

ComboFix /u



This will also reset your restore points.

How is the machine running now?

Ok I uninstalled combofix and everything has been running fine for the past couple of days since combofix removed everything including the rootkit which was the main problem. Thanks alot guys for your help.
