Downgrade AVG back to the Free version

 

AVG Free Antivirus is a great, free antivirus solution made by AVG Technologies.  Many people use AVG, and I have come across a few clients that have accidentally upgraded their Free version to the Paid 30 day Trial version, causing headaches.

 

downgrade avg

 

The problem occurs when updating AVG Free, and clicking ‘Next’ through a series of screens.  On the “Select your product” screen, AVG have pre-selected the “Internet Security Trial/Full Protection” option, which will upgrade you to the paid trial version of AVG.

To avoid this situation, you need to select the “Anti-virus Free/Basic Protection” button, before clicking ‘Next’.

Clients regularly ask if it possible to downgrade AVG back to the Free version.

Yes, if you have accidentally upgraded your AVG Free to the AVG Paid Trial, you can downgrade AVG back to the free edition by starting to uninstall AVG.  During the uninstallation process, you will be given the option to downgrade AVG back to the free version.

 

  • Open StartControl Panel, and then click Programs and Features.
  • In the list of installed products select AVG, and then click Uninstall.
  • Click the option Switch to AVG AntiVirus FREE.

 

An AVG installer will run, and downgrade AVG to the FREE version. Wait for the installation to finish, and then restart your computer.

 

 

USB stick pictures

usb stick pictures

Some clients recently noticed all my memory cards and USB sticks have pictures, making it much easier to identify which stick is which when trying to save a file on to one.

 

This can be performed using Windows autorun pictures.

To complete this, you’ll need a picture in icon (.ico) format.  You can either download an icon file, from sites such as https://www.iconfinder.com or make your own icon from any picture, using an Icon Editor program such as Greenfish Icon Editor Pro.

 

Step 1Verbatim 32GB Store N Go USB

Locate a picture of your USB stick.  I try to find an exact picture of the stick, using a Google Image Search.  In this case I searched for “Verbatim 32GB Store n Go USB”

View the picture, Right click on it and select ‘Save picture as’, and save it to your desktop.

 

Step 2

To transform the picture in to an icon file, I used Greenfish Icon Editor Pro.  The video below demonstrates how easily that’s done.

Save the icon file directly into the USB stick, as ICON.ICO, making sure you save the file in ‘.ico’ icon format.

 

Step 3

Create a text file on the USB stick, called AUTORUN.INF which contains the following code:

[autorun]
icon=icon.ico

 

*Some additional notes about autorun are at the bottom of this post.

Step 4

Finally, I make both the icon and autorun files read only and hidden, using Windows Explorer – selecting both files > Right click > Properties and ticking the Read Only and Hidden check boxes.

All done – Just remove and remount the USB drive to see your changes.

 

Video Tutorial

The following video demonstrates how it’s done.

 

YouTube  Video URL: https://www.youtube.com/watch?v=YprCOwTUlns

 

Note: The same method can also be used to identify Memory Cards and Hard Drives.

 

Some notes about autorun:

The autorun feature has many more options, such as the label option, which names the USB stick – eg: “label=MyUSBDrive”.

 

Autorun is quite an old feature, first introduced with Windows 95.  The option commonly abused is the “open=Setup.exe”.  This has been abused to automatically run malicious software, without the user knowing.

This was patched at some point during the life of Windows, and Windows must now be configured to allow Autorun.inf to launch items.

An Autorun command reference is located at: https://en.wikipedia.org/wiki/Autorun.inf

 

Raspberry Pi Webcam Server

Raspberry Pi Webcam Server - Raspberry Pi Logo

Raspberry Pi Webcam Server Project

 

The Raspberry Pi is a small, cheap mini-computer that runs Linux.  It’s great for tinkering with, and there are many projects online to try.  In this project, I have used Linux ‘motion’ software to setup the device as a Raspberry Pi Webcam Server.

Raspberry Pi Webcam Server - Raspberry Pi

 

Project Definition

The Raspberry Pi Webcam Server will need to monitor and detect movement and will initially be set to record .AVI video files to its 16GB SD Card.  This folder will be open to the network for easy viewing, transferring & deleting of the recorded video files.

Logitech_c615_general_view_4_1In a future revision, the Raspberry Pi Webcam Server will be modified to save directly to either an attached USB hard drive or another networked PC share folder.

The video footage will also be streamed live to my local network and available through the browser on any device.

 

Ingredients

To complete this project I used:

  1. A Raspberry Pi
  2. A SanDisk Ultra 16 GB Class 10 SD Card
  3. A Logitech C615 HD webcam
  4. An externally powered 4 port USB hub
  5. A Logitech MK320 Wireless keyboard & mouse

 

Raspberry Pi Webcam Server Project - SD Card

Booting the Raspberry Pi Webcam Server

I chose to prepare the SD card using a Windows PC.  This involved downloading an SD card image from the Raspberry Pi website for free.

To place the image on to the SD card, I used Win32DiskImager for Windows.

Once completed, I inserted the SD Card into the Raspberry Pi and connected the externally-powered USB hub, Keyboard adapter and LAN cable, then I turned on the Raspberry Pi.

 

Setting up the Raspberry Pi Webcam Server

The standard Login and password for the system is username: pi and the password: raspberry

After logging into the Raspberry Pi, the first step was to configure the Raspberry Pi using the Raspi-Config tool.  I expanded the Root FileSystem, set the correct Time Zone and Locale, Enabled SSH, and set the device to Boot to Desktop option.

Tip: The Raspberry Pi can be reconfigured by running the following command from a terminal window:

sudo raspi-config

I also experimented with overclocking the Raspberry Pi and settled on the medium overclocking choice of 900MHz.

 

Now that the Raspberry Pi boots to the desktop, the next step was to ensure the Raspberry Pi operating system is up to date, using:

sudo apt-get update
sudo apt-get upgrade

I then downloaded and installed motion and ffmpeg

sudo apt-get install motion ffmpeg

and installed samba

sudo apt-get install samba samba-common-bin

 

I created a folder on the Raspberry Pi SD Card where motion will save the .AVI videos to.

sudo mkdir /home/pi/motion

sudo chmod 777 /home/pi/motion

I then edited the Samba configuration file to add the motion folder as a Network Share.

sudo nano /etc/samba/smb.conf

After entering the correct network details near the top of the Samba configuration file:

workgroup = MyNetwork

wins support = YES

I then added the following text to the bottom of the Samba configuration file.

[motion]

 comment=RaspberryPi Motion Share

 path=/home/pi/motion

 browseable = yes

 writeable = yes

 guest ok = yes

 

A quick check from another PC on the network confirms the folder is now visible.

Raspberry Pi Webcam Server - Network Share

 

Configuring the Raspberry Webcam Server

Now the Raspberry Pi is ready for me to setup the Motion configuration file:

sudo nano /etc/motion/motion.conf

I set the following items

daemon on

framerate 2

output_normal off

ffmpeg_cap_new on

ffmpeg_video_codec mpeg4

target_dir /home/pi/motion

webcam_port 8081

webcam_quality 90 

webcam_localhost off

control_port 8080

control_localhost off

Here’s a copy of my completed motion.conf

The full list of Motion Configuration Options are listed here:

http://www.lavrsen.dk/foswiki/bin/view/Motion/ConfigFileOptions

 

Next, I enabled the motion daemon by editing this configuration file:

sudo nano /etc/default/motion

and I changed start_motion_daemon=NO  to

start_motion_daemon=yes

 

Now start the Motion server service:

sudo service motion start

 

To restart the motion software following changes:

sudo /etc/init.d/motion restart

 

Rather than using a WiFi adapter, I have chosen to use an existing Netcomm NP-204 Broadband Over Powerline adapter, which will provide power and LAN cable internet connection to the Raspberry Pi.

 

Netcomm

 

I had already set my Network Router to provide the Raspberry Pi with a static IP address of 192.168.1.20 for previous projects.  The picture below shows that Address Reservation in the Router Configuration webpage.

 

Raspberry Pi Webcam Server - Router Addresses

 

Now any network connected device, including PCs, Tablets and Smart Phones can now browse to 192.168.1.20:8081 to view the live stream of images from the Webcam.

To remotely configure the motion server, I browse to 192.168.1.20:8081.  The image below is a screenshot taken on a Samsung Galaxy running Firefox for Android.

Overheating PC tips

Overheating PC - Hot LaptopIn this hot weather we know to keep ourselves, our children and our pets cool, but its also a good time to check on your PC’s health – perhaps its an overheating pc

 

Computers will shutdown when they are too hot, in an attempt to protect themselves from excessive heat damage, but permanent damage can still occur.

 

How do you check the PC’s temperatures ?

The majority of PC’s show their temperatures in the BIOS screen, but this requires a reboot to access it.  It’s much easier to view the PC’s temperatures by downloading and installing SpeedFan v4.49, a FREE tool available from the Tailormade IT Solutions website:

http://www.tailormadeitsolutions.com.au/tools/SpeedFan-v449-Installer.exe

“SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips.”  Source: http://www.almico.com/speedfan.php

 

If you do notice high temperatures, or are experiencing strange shutdowns and outages, this can result in permanent damage to your PC, and reduce its life span.

Tailormade IT Solutions recommends and provides PC maintenance services that investigate and resolve overheating PC issues, including:

Dust Removal Dust is a great insulator, and cleaning out that build up of dust inside the PC will help it breathe better and run cooler.

Fan ChecksEnsuring your internal PC fans are not damaged, and are working correctly and effectively removing heat from the PC.

CPU Thermal PasteThe PC’s brain, or CPU, generates a lot of heat.  Checking and reapplying the Thermal Paste on the CPU can assist heat removal from this important component.

Additional CoolingInstalling upgraded or additional heatsinks and fans, including water cooling for extreme desktop PCs.  Laptop owners can also purchase laptop cooler pads.

 

 

Please note that the following method of cooling your PC is NOT recommended.

Avoid banking trojans

There are reports that a new bank account raiding Trojan, called Hesperbot, is doing the rounds.  This Trojan uses an old design flaw, found in ALL versions of Microsoft Windows.

Credit Cards

 

These viruses try to trick users into running a malicious Windows executable, cunningly named with a .pdf.exe file extension.

For example, a program named “MyTrojan.pdf.exe” will show as “MyTrojan.pdf” to most Windows users.  With the addition of a PDF icon, users are duped into opening what they think is a PDF file.

 

These type of attacks can be easily vaccinated against with one simple change of settings:

Set your Windows Explorer to show the extensions for known files.

WinExp

There are a number of ways to access these settings – such as using the Control Panel / Folder Options / View Tab, or from inside Windows Explorer / View / Options / View tab.

Microsoft continues to hide extensions by default.  If only they set Windows to show extensions by default, this attack vector would not exist.

 

Backup

Backup Routines

 

BitTorrent Labs has just released a new tool called BitTorrent Sync, which is used to sync files/folders from one PC directly to another.  It works differently to cloud based products like Dropbox, Google Drive, and Microsoft Skydrive.

With a variety of backup options now available, its surprising that many users don’t consider backing up important data until its too late.

In this post, Tailormade IT Solutions discusses backup options and some of their pros and cons, including their ease of use, safety, security and suitability.

 

Tailormade IT Solutions can configure a backup routine that ensures your data is safe.

 

Copy Files Locally

I’ve met users who simply plug in a USB drive and copy data from their computer manually.  For example, copying the My Documents folder to a USB drive, CD or DVD.Backup to USB stick

Pros:

  • Simple.

Cons:

  • User has to remember to backup regularly;
  • backup data is held on-site and susceptible to physical loss.

 

Automated Backup – Locally

The next step would be an automated backup solution.  Data is a lot safer if the backup routine is automated and regular.  These backup routines typically work at a certain time, and copy information to a USB drive.  Users should disconnect the backup drive when not in use.

Pros:

  • Set and forget peace of mind.

Cons:

  • Data held on-site.

 

Automated Backup/Sync over Network

If you have multiple computers, your can set one aside as a backup PC, and configure all other computers to backup at a certain time to that location.  This can work locally or through the internet, using the new BitTorrent Sync tool.

BitTorrent Sync Logo

Pros:

  • Set and forget peace of mind.

Cons:

  • Data held on-site.

 

Automated Backup/Sync to Cloud

Using cloud storage providers (such as DropBox, SkyDrive or Google Drive) to syncing folders has become very popular.  These services allow you to automatically sync a folder from your computer to a internet server.  With your login details, the server can be accessed from any computer in the world.

Cloud storage providers offer varying levels of service and security, but they also retain ownership of your data in the fine print, and  commonly limit the sizes of files you can upload, and/or total server size.

Pros:Backup - Cloud Storage providers

  • Data is held off site, and accessible from anywhere in the world.

Cons:

  • Data held by cloud providers is owned by cloud providers.

TPB AFK

TPB AFK logo

 

On 8th February 2013, a new documentary was released directed by Simon Klose.  The documentary “TPB AFK – The Pirate Bay Away From Keyboard” is based on the lives of the three founders of The Pirate Bay – Peter Sunde, Fredrik Neij and Gottfrid Svartholm.

Of course, The Pirate Bay is one of the best known file-sharing brands and the site has a well-earned place in Internet history.  Swedish filmmaker Simon Klose has documented part of their struggle as they are targeted by several court cases over the years.

What not many people know is that the three founders of The Pirate Bay often pretended to get along in public, but had some big fallouts in private. This becomes quite apparent in the documentary.

TPB-AFK is the first film to premiere both online and at a major film festival, and can be downloaded and shared for free.  The full film is released under a Creative Commons license onto The Pirate Bay and other BitTorrent sites.  3 versions of this documentary are legally available for download from the Pirate Bay website.

The film runs for 122 mins.

Android Portable Wi-Fi Hotspot

 

android wifi hotspot - Optus Mobile Internet

Why pay for a separate Mobile Internet connection for your laptop, when your phone already includes a Data Allowance ?  A few people answer: Because I don’t know how to setup an Android WiFi Hotspot.

This is a short guide on how to setup a Portable Wi-Fi Hotspot on your Android phone, and connect a Windows laptop to it.

You can then cancel your laptops Mobile Internet connection and save a few dollars.

Android Wifi Hotspot

Step 1: Configure Wi-Fi hotspot on Android phone

In the Android phone settings you will need to find the “Tethering and portable hotspots” menu.  In this example (using a Samsung Galaxy S2 running Android 4.0.3) it is found by tapping the Android Settings button from the main screen, then tapping “Settings”, then “More” and “Tethering and portable hotspots”.

Android – Windows Networking

ES File ExplorerAndroid phones come with a built-in file explorer, called “My Files”, but this app can only browse the phones memory card.

To improve your Android Windows Networking and copy files easily across the network, download and install a free app such as ES File Explorer, available from the Google Play Store.

 

First, lets setup a Network Share folder in Windows, which will be visible on the network, and to the phone.  Once set, Windows will remember this share setting.

On your PC, using Windows Explorer, browse to the folder you want to share.  In the example picture shown below, I am using the ‘New Folder’ on the desktop.  (Click on the image below to zoom in)

 

Windows 8 Network Share Folder

To setup a folder as a Networked Shared Folder in Windows:

  • Right-click on the folder you want to share.
  • Choose ‘Properties’, and then the ‘Sharing’ Tab.
  • Click on the “Advanced Sharing’ button.
  • Select the “Share this folder” checkbox, and enter a name.
  • Click the ‘Permissions’ button.
  • Select ‘Full Control’.
  • Click ‘Ok’, ‘Ok’ and ‘Close’.

Tip Icon 2

This folder is now visible on the network and you can access (read and write) this folder from other network devices.  You can repeat this process for multiple folders on multiple devices.
