Android Malware Detection Provides False Security (Technology)


Today I'm going to discuss adware. Adware is contained in software to generate revenue for the software company. It pushes advertisements of apps and other products, which consists of marketing propaganda designed to evoke emotions in the targeted audience, who are technology consumers.

On an Android smartphone, advertisment revenue generated by adware is shared between Google and app developers for apps offered on the Play Store and by third party providers. Play Store also offers apps to detect adware, but sometimes its detection is misleading.

As an example of this, the antivirus app AVG gave a false positive for Play Music on my smartphone. When I checked out AVG Threatlabs for this "threat", it stated: "Beware of Adware! No potential malware has been detected for this android app for the last 7 days. However, active adware was detected. ( Last updated: Jul 14, 2016 )".

Gee, thank you, AVG; I know all apps have active adware.

As an AVG subscriber, my use of AVG and AVG Zen (a Device Manager clone) provides the company with monthly and yearly revenue, just so they can tell me adware is active on my devices.

It sems as though I'm paying for a false sense of security. So the easy fix is to cancel my subscriptions to AVG and avoid clicking on ads that seem sketchy.

According to the AVG Threatlabs website, Play Music contains active adware: as part of Google's marketing scheme, it is also being included with other useful software for smartphones (Android and iPhone) and desktop computers.

Yet Android adware is included in almost all apps on Google Play Store. Therefore the AVG Threatlabs message that warns me to "beware of adware" is a scare tactic used by the company to influence users of the AVG products to subscribe to their service.

My, how subtle is the marketing propaganda for AVG is.


Here are optional instructions on how to turn off access to unknown sources of Android apps and how to opt out of ads targeting you. Disclaimer: I take no responsibility for what you do after reading these instructions.

Only two things need to be done:

1) Turn off access to third party providers Unknown Sources) of Android apps by turning that setting off in System Settings: Security under the heading Device Administration. The Unknown Sources option should be deactivated. If it's not, then I am going to assume you know what you are doing.

Optionally, you may want to control what ads you see.

2) In System Settings: Google: Services: Ads, you may opt out of interest-based ads and click on Ads by Google which will run Chrome, loading Ad Settings.

Note: Opting out won't completely stop ads — the Android Central article about Android Malware Scanners article provides details.

Preparing Nexus 4 for Android 5.10 Upgrade



Synopsis: to prepare your Nexus 4, first wipe cache partition and then upgrade to Android 5.10.

  • Wiping Cache Partition
    1. If your phone is on, hold the Power button to restart it.
    2. Hold the appropriate device-specific buttons until you see the word "Start" in green and a large Android robot on its back.
      On the Nexus⁴: Press and hold the Volume Down, Volume Up, and Power buttons at the same time for several seconds.
    3. Press the Volume Down button twice to highlight "Recovery mode," then press Power button. The words "Google" will show on the screen followed by an image of a small Android robot on its back with a red exclamation mark and the words "No command."
    4. While holding down the Power button, press the Volume Up button. Some menu options will appear.
    5. Use the volume buttons to scroll to "wipe cache partition" and press the Power button to select it. It takes up to 10 minutes to complete the process. Problems can occur if one is impatient and attempts to reboot during this process, so it's best to just let it complete.
    6. After the cache is wiped, scroll to "reboot system now" and press the Power button again to restart the device.
  • Note: If your phone becomes unresponsive at any point during these steps, you can restart it by holding down the Power button for several seconds.

To make the above instructions more meaningful, on Youtube is this video on how to wipe the cache partition on the Google Nexus 4.




After clearing the cache, download and install the Android 5.10 OTA update.


Commentary: after wiping the cache partition, I upgraded my Nexus 4 to Android 5.1 without any issue.

'Casting Content (poem)

'Casting on the net is fun,
Wherever you are,
When you are doing it right.
For who can complain,
When consuming media?

Once, it used to be text, see?
With a modem,
I dial up a BBS —
Today, it is texting —
SMS and MMS.

Yet with two Android smartphones
You broadcast on TV —
Your forty-inch TV —
Pictures, music, and
Even videos — great, eh?

Even so, 'casting is new,
So new that it's like 1969
And Star Trek is in color —
'Casting is like that —
Lost in Space in monochrome.

That is modemming —
Lost in cyberspace back then
When it was all new
And shiny like the first kid
With color TV — great, eh?

One day, broadcasting content
Will be old — what then?
What will be the new toy, eh?
3D using your smarphone
With a thirty dollar toy?

Data Clouds (satire)

After reading that the Chinese government said Ubuntu, Windows and Android are not safe, I went to Google "EU and computer security Ubuntu" to see what I could learn to confirm this.

According to what I found, UK's security branch says Ubuntu is secure, and the Dutch concur.

However, data stored on cloud servers is vulnerable to US Patriot Act. See this article for more information: http://askubuntu.com/questions/58821/how-safe-is-eu-based-ubuntu-one-cloud-data

IMO the safety depends on the OS used.

Android is as safe as the smartphone owner wants it to be, without the complication of entering a throw-away password everytime I boot up my Linux PC. I don't rank securing my data on my smartphone as high as I do on my PC.

As for Windows, a weekly backup onto an external hard drive is recommend from the My Documents folder.

My security trick is I never save pictures I did not create unless it is related to a post on G+, and rely on G+ to store my photos safely. When Photos gets full, I look for the oldest pictures to back up. Sometimes I even purge old pictures if necessary.

Yes, I use G+ as backup for my photos. Drive could be used to archive the oldest album when I run out of space. Since Drive is a Google cloud, I consider it as a temporary file storage area to store these files until I need to store it on a flash drive or on CD-R or DVD-R disc.

However, I am not concerned because it's not full yet. Also, I can always start from scratch in the case of Google+ losing my pictures. That was the reason why I used G+ to backup my photos.

Of course, when I last upgraded my system in December, I used a partition I have created for the purpose to backup almost everything in my user directory. Currently that consists of about 25 MB on my current installation.

Now is the time to backup to format my backup partition and begin the long process of backing up my pictures.

My Next Music Album (satire)

In this article, I am going to write about the creation of my next music album. With the help of two Android apps on my Nexus 4 smartphone and four Linux programs on my PC, a song is created using two source audio tracks derived from two video files created by one of the apps.

Please note that I have used javascript code to hide and show text depending on the familiarity of my followers with the Android apps and Linux programs mentioned in the rest of this article.

None of the links in the main text of this article will crash your computer and the link at the very end of the references points to the author of the code.

My reason for calling this article satire is that I could have written it without hiding any text at all. Then it would have only made sense to a fellow Linux hobbyist who also owns a smartphone with the same specifications as a Nexus 4, and wants to use the Android apps and Linux programs mentioned in the main text to create song too.

Currently I am using my smartphone to create my next album, Sound of Colors Remixes with the help of the Android app, Color Sounds.

Using the Camera option of Color Sounds, I can create two Flash videos in which the video stream is used to create the audio stream of each video.

Once the videos are made, they are transferred to my PC using Bluetooth.

Once the video files are on my PC, I convert them into MP3 audio files using the audio conversion program Gnac.

After the audio files are created on my PC, I note the time length for each video using the sound editor Audacity.

Then pick one of the audio files to be the main source track and adjust the time length of the remaining file to match the main source track. Next import the remaining audio file and perform "Mix and Render" on both tracks.

Create your song with a time length of between three and six minutes long.

It is feasible to use Color Sounds on your smartphone to create a three to six minute movie if you have the room on your smartphone.

Then you could just convert the videos made to an MP3 audio file and use that as the source audio stream for your song.

However, the larger size of the video file would result in long wait times for the resulting audio file.

Therefore it is recommended to create video files of no longer than a minute at the most. Then convert to audio files, and use them to create your songs.

Android Apps at Google Play:

Both apps work on a Nexus 4 smartphone running Android version 4.4.3. Please test them out and see if they work on your smartphone.

Predicted Dates for Android 4.1 (Jelly Bean) and 4.2

After the upgrade to Android 4.0.4 in late August 2012 for my smartphone, I thought I had the best upgrade ever.

Now with Android 4.2 on its way, my prediction for upgrade to Jelly Bean via my provider is within a year (by October 2013) and Android 4.2 by March 2014

Since these are predictions about when my provider will upgrade Android, I continue to wait patiently until the upgrades get pushed to my phone.

When those upgrades happen, I'll make a note of them in this blog entry.

Fix: Acer Liquid E - SMS working but no Internet

NOTE: do not try the factory reset procedure mentioned in this article without contacting the support team of your mobile carrier. Also the Lookout app recommendation is not a product endorsement.

For the week before April 23, my Acer Liquid E smartphone stopped allowing 2G & 3G data access to the mobile network.

Rebooting didn't work: I'd get 15 seconds of data access, and then it'd stop.

At this point, I decided that my goal is to make my smartphone work with help from my mobile carrier's support team (Basic Support and Tech Support).

After calling my mobile carrier's Basic Support line, I was instructed to reboot my phone and call back on a landline if that did not work.

So I rebooted my smartphone again. No go.

Then I called back on a landline, and was handed over to Tech Support who talked me through the factory reset procedure.

Overall time spent fixing this: about thirty minutes.

Goal attained: a working smartphone!! :)

Note: the mobile carrier support asked for ID information to confirm my ID and to give directions to confirm my ownership of the smartphone (IMEI #). I freely complied with the support team to attain the goal of a working smartphone.

Because Google has an open source policy on Android apps, it's possible for malware to get into the Android Market. This happened recently when 21 apps were removed after Android users complained about the problem.

The Lookout Mobile Security app may be useful for detecting the DroidDream rootkit malware which led to apps being removed.

However, it requires your gmail address and a password (NOT YOUR GMAIL PASSWORD) to backup data (contacts, call history & pictures) and locate a missing phone.

Lookout also gives you the option to use the backup and missing phone features. After using it, I realized that the following security procedures renders the use of Lookout moot, save for the missing phone feature.

A working smartphone must be lean in apps. This especially means NO GAMES. I state this because I used to randomly play a game app for hours until I got bored with it, only to delete that game and randomly pick another game I liked.

As well, website browsing should be limited to safe sites. This means NO PORN SITES because the majority of them may have java malware to compromise Android security.

In order to ensure that my phone keeps working, I can live without games and porn. As well, I will reduce the number of high risk apps on my phone.

To ensure that my smartphone never ends up stolen, I make sure to use it discreetly.

my first blog post via my Android

January 30, 2011:This is awesome.

I'd write more but the XT9 keyboard demands more pause for reflection.

In the future, comments like above will become as verbose as this comment. Only time will tell... :)
