Please download Combofix:
And save to the desktop.
Close all other browser windows.
Please connect all your external hard drives/flash drive before running Combofix
Important-> Temporarily disable your anti-virus, real-time protection before performing a scan. They can interfere with combofix or remove some of its embedded files which may cause "unpredictable results".
Double-click on the combofix icon found on your desktop.
Please note, that once you start combofix you should not click anywhere on the combofix window as it can cause the program to stall. In fact, when combofix is running, do not touch your computer at all and just take a break as it may take a while for it to complete.
When finished, it will produce a logfile located at C:\combofix.txt.
Post the contents of that log in your next reply with a new hijackthis log.
Please copy and paste your log files. DO NOT add it as an attachment
