When I start the computer, about half of the processes load immediately, including winlogon.exe and svchost.exe -k netsvcs which utilize dmocxn.dll. After 3 to 5 min. the firewall is disabled and the rest of the processes are loaded.

I suspect dmocxn.dll as the problem since it does not return google results. Additionally a service titled "xubzgrdt" is loaded under the svchost.exe - k netsvcs process pointing to dmocxn.dll as the servicedll in the registry.

As seen in the HJT log, dmocxn.dll is also used in the winlogon.exe process and points to a Internet Explorer addon which I have disabled.

I cannot manually delete dmocxn.dll and when I use HJT to delete on reboot, it either does not delete or replaces itself on startup.

Additionally, deleting the registry entries where dmocxn.dll is specified only causing them to reappear on reboot.

When I disable the xubzgrdt service in Control Panel/Administer Tools/Services, it reverts to automatically loaded and sometimes changes the description.

I suspect some process or file is resetting these services, but i cannot detect any strange processes besides those described.

When I try to manually restart the Windows Firewall, it gives me "Error 2001: The specified driver is invalid."

My network connection does not have an IP address and Windows give an error when trying to repair the connection that it cannot query the TCP/IP settings.

Because the computer cannot connect to the internet, I am using a second computer to post this.

Any help would be appreciated as I'm at the end of my methods.

Hey Richie,

Thanks for replying. I haven't booted up that computer since posting so the HJT log remains the same. Also in case you're wondering, there is no anti-virus software in the process list because I've disabled it after scanning to try to simplify the problem while debugging (or de-malwaring).

The description in the previous post is pretty much all I know. Let me know if you need any additional information.

If you have previously downloaded ComboFix,please delete that version now.

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 by sUBs and save to your desktop.
Alternative Combofix download link HERE.

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.
