Solution: Can't Browse the Internet After Installing / Upgrading AVG Anti-virus | How to Remove AVG Miniport

-
Problem:
Can't browse the Internet after installing or upgrading AVG 9.0

Symptoms:
  1. In some system, Local Area Connection (LAN) says the cable is unplugged even though it is plugged in.
  2. IPConfig command returns nothing.
  3. In the Device Manager under Network Adapters, there are several entries of AVG miniport driver and these entries have yellow exclamation mark. ("WLAN Miniport (IP) - AVG miniport driver")
  4. Properties shows: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Click Troubleshoot to start the troubleshooter for this device."
  5. You cannot uninstall the AVG miniport driver entries (remove or delete). Update and rollback doesn't work either. System Restore will not help.
Screenshot:

Culprit:
The devices appear because they are called up by registry entries which should have been deleted as part of the AVG uninstallation

Solution:
Uninstall your network adapter (the one without exclamation mark) and install it again. This usually solves the internet connection issue but the AVG miniport driver entries still exists.

How to remove AVG miniport driver entries in Device Manager:
Try any of the following solutions:
  1. Go to Network Connections and disabled then re-enabled Firewall protection for your network connection.
  2. Download and use AVG remover. It is a cleanup utility provided by AVG to remove any trace of AVG antivirus.

Taken from: atmaxplorer.com I’ve been receiving tons of questions on how to check if their PSP can have custom firmware installed. Here’s a complete and concise guide to get you going. Make sure to read through the guide fully since it will answer all your psp motherboard related questions. First of, you need to understand that there are three types of PSPs: 1) 1000 Series (Also known as PSP Phat/Fat) 2) 2000 Series (Also known as PSP Slim or Lite & Slim) 3) 3000 Series (Also known as PSP Brite) So why install Custom Firmware on a PSP? People install Custom Firmware so they can run Homebrew, programs developed by people that don’t have a contract with Sony. A PSP with Custom Firmware could also back up your games from the UMD to your computer; it also allows you to play those backups from your Memory Stick (MS). You could also do some serious customizations to your theme. Basically, you free your PSP from the hands of Sony. Why can’t I install Custom Firmware on my

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged (code 19)- CD ROM Device Manager Error One of my client brought in a Dell Latitude laptop that has a problem with its CD ROM. According to the owner he can't access his CD. The model of his CD Rom is Samsung CD ROM SN-124. Upon inspection, I found out that the device (CD ROM drive) is missing from his My Computer (as you can see on the image below) At first, I thought that the problem lies with the connection of the CDROM because I had it disassembled a week before due to display problem. The CD Rom is snap in type, so I easily took it out and back in without hassle. Upon logging in to windows, the problem still persist. Next, I checked the Device Manager (right-click My Computer, choose Properties, then Hardware and click on Device Manager). As you can see on the picture below, there is a problem with the CD ROM because there is a yellow exclamation mark befor
