I am new to your site and found it after my PC was hijacked by Total Security.
I followed the instructions to fix the problem with Combo Fix after I removed the Isass.exe file from the systems registry. Combo Fix detected a few more files, deleted them from the computer, and after restart a log was created.
At this point I tried to connect to the internet but the computer failed to recognize the wireless connection and instead is defaulting to dial up mode (I do not have dial up subscription).
The ComboFix instructions on your website suggest repairing the wireless connection through control panels if one runs into this problem. I followed the instructions and repaired the connection, but still no internet. I rebooted, still no internet.
I tried to restore back to a date in July pre-hijack (could never get this far before running ComboFix) but the system said it could not restore back to the date.
Help!!!!!!!!! I dont know if I have a corrupted driver for the wireless card (which checks out "ok" via XP) or if I lost a file during the ComboFix but I am dead in the water with the PC - can someone help me out of this death spiral?

Welcome to BC

Try this for your internet, try this

Log on as an administrator, go Start > Run and type: "cmd". In the window that appears type: "netsh winsock reset". When the program is finished, you will receive the message: "Successfully reset the Winsock Catalog. You must restart the machine in order to complete the reset." Close the command box and reboot your computer.

Go Start > Run > type: "cmd" In the window that appears type: "ipconfig /flushdns". Close the command box.

Go Start > Control Panel > Network Connections. Right click on your default connection, usually Local Area Connection or Dial-up Connection if you are using Dial-up, and and choose Properties. Double-click on the Internet Protocol (TCP/IP) item. Select the radio button that says "Obtain DNS servers automatically". Reboot.

Warning: Some Internet Service Providers need specific DNS settings. You need to make sure that you know if such DNS settings are required before you make this change.

As I hope you have read in the Combofix disclaimer, this is no support for Combofix

One of the reasons it is not recommended to use ComboFix without supervision is because of these kinds of problems, as you already know. What hasn't been pointed out is that, if you had had supervision, your helper could have gotten in contact with CF's author to resolve the issue. He won't do that with people who ignore the disclaimer and run it on their own--he uses his time to make CF better.
