|In some instances, access to an Internet connection after running ComboFix is gone.|
See if the following steps help:
Using your home computer (if this is where ComboFix was run), go to Start > Control Panel
Double-click on the Network Connections icon. (If your Control Panel is set to Category View, then double-click on Network and Internet Connections and then click on Network Connections at the bottom.)
You will now see a list of available network connections.
Locate the connection for your Wireless or LAN adapter and right-click on it.
Click on the Repair menu option.
Let the repair process perform its tasks and when it finishes, your Internet connection should be working again.
Alternatively, if your network icon also appears on the Windows TaskBar, repair it by right-clicking on the icon and selecting: Repair
At home, do you use a WPA or WEP security protocol?
