Welcome to the BleepingComputer HijackThis Logs and Analysis forum Howe
My name is Richie and i'll be helping you to fix your problems.

If you have previously downloaded ComboFix,please delete that version now.
Warning
You should NOT use Combofix unless you have been instructed to do so by a Malware Removal Expert.
It is intended by its creator to be used under the guidance and supervision of an expert,not for private use.
Using this tool incorrectly could render your system/pc inoperable.

Now download Combofix and save to your desktop:
Note
It is important that it is saved directly to your desktop

Close any open browsers.
Double click on combofix.exe and follow the prompts.
When it's finished it will produce a log.
Post the entire contents of C:\ComboFix.txt into your next reply.
Note
Do not mouseclick combofix's window while it's running.
That may cause the program to freeze/hang.

Do NOT post the ComboFix-quarantined-files.txt unless I ask.
Note
In case your Antivirus or any other realtime scanner is displaying an alert after you downloaded Combofix or while you use Combofix,please disable your scanner and redownload Combofix again.
Some scanners may see some combofix related components as suspicious and block or delete them while there's nothing wrong with them.

Also post a new Hijackthis log please.
