Suggested March 2024 How To Remove A Virus From Your Android Phone

Viruses and malware are out there for every system. Don’t delude yourself into thinking otherwise, especially on Android, where just a few years ago it was reported by F-Secure that 97% of all mobile malware was based on the Google-owned platform. Most of these aren’t conventional PC-style “viruses,” however, but dodgy apps supported by scareware or poorly programmed in a way that negatively affects your device.

That all sounds a bit doom-and-gloomy, but don’t worry, because our guide here will help you steer clear of the bad stuff.

Remove a Virus Using Safe Mode

If you are suffering from unexplained power outages, a fast-draining battery, or other issues since downloading an app or a bunch of apps, you should first boot to safe mode where you can remedy the problem. In Safe Mode the OS won’t load any third-party apps you downloaded, and if you find your phone is working okay when you’re in Safe Mode, then you more or less know that you have an app that’s causing mischief.

The following is how to get into Safe Mode.

If your device is on: hold the power button until the boot options appear, then touch and hold the Power button until your device boots to Safe Mode or until you get asked whether you want to reboot to safe mode.

If your device is off: hold the Power button until the phone logo appears on the screen, then hold the Volume Down button until you boot into Safe Mode.

You’ll know you’re in Safe Mode by the small “Safe mode” label that appears in the corner of the screen. Now that you’re in Safe Mode, you should hopefully notice that your device is running smoother, faster, and is no longer blighted with scareware messages telling you to call premium numbers to protect your device. This, by extension, means that a third-party app was causing all those problems before.

A good rule of thumb here is to delete anything that isn’t from a developer you’re really familiar with. If you just downloaded a random game you found in the Play Store on a whim, or some obscure shopping list app that not many other people had previously downloaded, start by getting rid of those.

If you have time on your hands, delete one app, boot your device normally, and see if it’s working normally. If it’s not, go back into Safe Mode and repeat this process until you notice the problem stops (once you find it, make sure to give it a scathing review or even report it to Google by tapping the “Flag as inappropriate” button on its Play Store page).

How to Avoid Getting a Dodgy App Next Time

Unlike on PC, the vast majority of “antivirus” apps for Android, even from the biggest security software developers, don’t offer the same level of security you’d get on PC. Also, don’t believe that just because you download apps exclusively from the Play Store that you’re safe. Malicious apps regularly get past Google’s defences and are downloaded by users in the millions. Try to stick with apps that have plenty of reviews, high review scores, and are from well-known developers. (Malicious app developers tend to clone reputable apps, then pass them off under a different developer name, so be wary of those.)

If you’re not a confident Android user, try not downloading apps (or APKs) from unknown sources.

Always read the permissions that apps request of you. If a note-taking app wants your contacts’ information, or a simple game is requesting use of your camera, think twice before accepting.

Conclusion

Be careful with what you download, and always do your research on an app and developer before committing to the download – read reviews, see what other apps that developer has made. Thankfully, conventional viruses that replicate themselves using users’ devices are a non-entity on Android, but scareware and apps that can have a terrible impact on your Android experience are everywhere, and you need to be ready for them.

How To Protect Your Android Phone From Stagefright Exploit

If Stagefright sounds like a scary name, that’s because it is. Stagefright might just be the biggest exploit yet to have been discovered in Android. It stretches back to Android 2.2 Froyo, affects a vast majority of Android phones (around 900 million) and works via MMS. The recipient, in this case, doesn’t need to do anything. If they’re using Hangouts or the default Messaging app, the app will automatically download and process the MMS for playback. And that’s all the exploit needs to infiltrate your phone.

Stagefright is a core library in Android used to play multimedia files like MP4 videos. The reason Stagefright is so scary is because it makes the process of sending malicious code to an Android phone really easy. This malicious code can be anything the hacker wants it to be. Here’s a video of how the exploit works.

How to Check the Vulnerability of Your Device

Google has already patched the bug in the latest Android release (so if you’re using the flagship Samsung and Moto phones, you should be fine), but the problem is that not everyone is always running the latest version of Android. You’ll need to rely on the manufacturer to push an update.

The company that exposed the bug, Zimperium, has also released a simple app, Stagefright Detector, for testing if your phone is vulnerable. Just download the app and start the test. In a couple of seconds you’ll have your answer.

If you’re vulnerable, keep an eye out for the latest updates and upgrade as soon as possible.

Also, try the following solutions.

How to Protect Yourself from Stagefright

Unfortunately, because Stagefright is so deeply embedded in Android OS, there’s no tool to just disable the feature. Instead, we’ll need to use workarounds.

We know that the exploit is only activated when the MMS is downloaded automatically on your device. Let’s disable that feature.

Messenger by Google: if you’re using Google’s Messenger app, tap the three-dotted-menu button and select “Settings.” Go to “Advanced” and disable the “Auto-retrieve” option.

Messaging: If you’re using an older version of Android, it probably came with the Messaging app installed. Tap the “Menu” button, then “Settings”, find the “Multimedia (MMS) messages” section and uncheck “Auto-retrieve.”

No matter which SMS app you’re using, there should be this option somewhere in the settings. Look for it and disable it.

If you’re really paranoid, you can just disable text messages from unknown contacts if your SMS app supports the feature.

Now the app will no longer auto download MMS.

If you live in an area where MMS messages are still prevalent, just don’t open the MMS messages from people you don’t know.

This is your best defense right now – that is until you get the patched update. If you want to take matters into your own hands, you can just root your phone and install CyanogenMod (or other CM-based ROMs) to make sure you get prompt security updates. CM has already fixed the bug in the nightly version, and it should be out in the stable release soon.

How To Make Your Android Phone Look Like A Windows Phone

Windows Phone is dead. It’s been a long time coming, what with Microsoft’s mobile platform being born with the fatal defect of “Not Android or iOS Syndrome.” The Windows Phone had some noble ambitions, trying to fuse itself seamlessly with the PC version of Windows, but in the end it just didn’t get enough support. However, there are some things from the Windows Phone that are worth keeping, and luckily many of them are available in one form or another on Android.

Here are the tools and apps that will keep a piece of that Windows Phone magic alive, long after it’s gone to the great mobile market in the sky.

Launcher 8 WP Style

The name of this app may be all over the place, but don’t let that deter you if you’re looking for a convincing tile-based interface, harkening back to the “glory” days of Windows 8. While the tile stuff didn’t really work out on desktop, it works very nicely on touchscreens, and you get all the joys of changeable tile sizes, Windows theming, and live tiles as well, which dynamically flip over to let you know when someone’s trying to contact you or when you’ve received an email.

SquareHome 2

Cortana

If you use voice assistants, then you’ll be aware that they largely define your mobile experience. Google Now (or Google Assistant as it’s come to be known) is Android all over, and if you want to truly get that Windows Phone experience (with the perks of Android’s customizability and Play Store, of course), you need to get Microsoft’s digital assistant, Cortana. It has much the same functionality as Google Assistant, is regularly updated, and syncs up nicely with Windows, too.

Here’s our guide to replacing Google Now with Cortana on Android.

A.I. Type Keyboard

A.I. Type Keyboard isn’t specifically designed to recreate the Windows Phone feel, but it has so many customization options contained in it that you can do just that. A couple of the free themes in this app are “Windows 8 Tablet Theme” or “Windows Phone 7 Theme,” which accurately mimic the dark look of the keyboards found on Windows Phone devices. If you fancy yourself as a bit of a designer, you can even customize the existing theme to your liking!

Microsoft Office

The trifecta of Microsoft Office apps – Word, Excel and PowerPoint – came to Android a couple of years ago, and it’s safe to say that they’ve been a great success. The polished look and feel of these apps makes them the very best that you can get on Android, and frankly their wealth of features puts Android’s native office suite – Docs, Sheets and Slides – to shame. A real masterclass of app design, this suite shows that even though Microsoft has bowed out of the hardware game on Android, it has a bright future on the software front.

Conclusion

With this lot, you’ll be able to pay fitting tribute to Windows Phone using your Android device. There was a lot to be said for Windows Phone, but it really didn’t cut it in the apps department, so here you get the best of both worlds. Even if you’re not that into Windows Phone (hence you’re on Android), it’s fun to tweak things, right? So do give it a go.

How To Remove Drm From Your Music And Movies

DRM is restrictive, annoying baggage that keeps consumers from doing what they want with their purchased media. Here’s how you can remove DRM from your music and movies using a couple software applications.

What Is DRM?

DRM, or Digital Rights Management, is a software solution to a copyright problem. When content is distributed on a disk without any kind of DRM, the end user can do anything they want with it. They can copy it a million times and sell it on the street for five bucks, save it to their hard drive, share it on the web and more. DRM tries to solve this problem by making it impossible to use content in specific ways. For example, DRM is what keeps movies purchased on iTunes inside of iTunes.

From the perspective of rights-holders, it sounds like a decent solution to a troubling problem. In the world of free online distribution of content, how else can creators protect their rights?

Unfortunately, DRM has a terrible track record. It ranges from pathetically ineffective to actively malicious, sometimes even both as in the case of Sony’s root kit DRM. It also tends to penalize legitimate consumers since pirates won’t have to deal with the manifold frustration of DRM-limited content.

The situation is so fraught that DRM, and the associated copyright laws have become a political issue with people rallying behind the removal of all DRM. And a world without DRM might not be that different from what we have today: the most common forms of DRM can be easily broken, and even new DRM schemes are quickly cracked.

Is Breaking DRM Legal?

The legality of removing DRM from media depends on your country of residence. In you’re a U.S. or U.K. resident, removing DRM from media is illegal. Elsewhere, it’s a bit of a mixed bag. Austrialian residents are permitted to copy protected media for “personal use” and Finnish courts have ruled that users can break “ineffective” DRM. Some E.U. member states, like Spain, have opted for a “personal use” exception similar to Australia’s rules.

Let’s be realistic, though. If you’re removing DRM from media you legally obtained for personal use, the chances of getting caught are virtually zero. Distributing content is another story. That’s illegal in no uncertain terms, and it’s also immoral, considering it robs creators of income from their creations.

In brief: Are you breaking the law? Maybe. Will you get in trouble? My magic 8 ball says no.

Remove DRM from Movies on Windows 10

We’ll be working with M4VGear for this tutorial which works specifically with iTunes, but there are plenty of other applications that will also remove DRM from music, movies, ebooks and more.

1. Download and install M4VGear.

4. Select the movie you want to remove DRM from.

Remove DRM from Music on Windows 10

We’ll use a different application from the same developer called Sidify to remove DRM from music files.

1. Download and install Sidify.

3. Select the tracks you want to remove DRM from.

Conclusion

Neither of these methods are free unfortunately and require purchasing expensive software. Right now there’s no reliable, easy and free way to remove DRM from your purchased media. But these tools, though expensive, work effectively and reliable.

Golang To Remove Null From A Slice

In this article, we will learn how to remove a null value from a slice using a variety of examples. A slice is a sequence of elements just like an array. An array is a fixed sequence of elements whereas a slice is a dynamic array, meaning its value is not fixed and can be changed. Slices are more efficient and faster than arrays moreover; they are passed by reference instead of value. Let us learn through examples how it can be executed.

Method 1: Using For Loop

In this method, we will see how to remove a null value from a slice using a for loop in an external function. Let’s see through the algorithm and the code how it’s being done.

Syntax func append(slice, element_1, element_2…, element_N) []T

The append function is used to add values to an array slice. It takes number of arguments. The first argument is the array to which we wish to add the values followed by the values to add. The function then returns the final slice of array containing all the values.

Algorithm

Step 1 − Create a package main and declare fmt(format package) package in the program where main produces executable codes and fmt helps in formatting input and output.

Step 2 − Create a main function and in that function create a slice with some values inside that slice including null values.

Step 3 − Create a function named removenullvalue with a slice as a parameter inside it.

Step 4 − Create an empty slice called result and this result will be used to append the non-nil elements inside it.

Step 5 − Run a loop till the length of the slice and in every iteration check if the element of slice is not equal to null append those elements inside the result and move to next iteration.

Step 6 − After the loop terminates return the output slice to the function.

Step 7 − The output slice will be printed on the console using fmt.Println() function where ln means new line.

Example

Golang program to remove null from a slice using for loop in the example.

package main import "fmt" func removenullvalue(slice []interface{}) []interface{} { var output []interface{} for _, element := range slice { if element != nil { output = append(output, element) } } return output } func main() { slice := []interface{}{10, 20, nil, 30, nil, 40} fmt.Println("The original slice is:", slice) slice = removenullvalue(slice) fmt.Println("The slice after removal of null value is:") fmt.Println(slice) } Output The original slice is: [10 20 30 40] The slice after removal of null value is: [10 20 30 40] Method 2: Using a Filter

In this example, we will see how to remove a null value from a slice using a for loop in an external function. Let’s see through the algorithm and the code how it’s being done.

Syntax func append(slice, element_1, element_2…, element_N) []T

The append function is used to add values to an array slice. It takes number of arguments. The first argument is the array to which we wish to add the values followed by the values to add. The function then returns the final slice of array containing all the values.

Algorithm

Step 1 − Create a package main and declare fmt(format package) package in the program where main produces executable codes and fmt helps in formatting input and output.

Step 2 − Create main function and in that function create a slice with non-nil and nil values.

Step 3 − Call a function named removenullelement with a slice as a parameter inside it.

Step 4 − In the removenullelement function call the filter function with slice and filter as inputs in it.

Step 5 − Inside the filter function, create an empty slice named output that will be used to append the elements of slice.

Step 6 − Run a loop until the length of slice and the filter function will return a new slice that satisfy the filter.

Step 7 − The returned slice will be obtained by removenullelement function which will use the filter function to remove all nil values from the slices and return it back to main function.

Step 8 − The new slice will be printed on the console using fmt.Println() function where ln means new line.

Example

Golang program to remove null from a slice using filter in the example.

package main import "fmt" func removenullelement(slice []interface{}) []interface{} { return filter(slice, func(i interface{}) bool { return i != nil }) } func filter(slice []interface{}, f func(interface{}) bool) []interface{} { var output []interface{} for _, element := range slice { if f(element) { output = append(output, element) } } return output } func main() { slice := []interface{}{1, 2, nil, 3, nil, 4} fmt.Println("The original slice is:", slice) slice = removenullelement(slice) fmt.Println("The slice after removing null element is:") fmt.Println(slice) } Output The original slice is: [1 2 3 4] The slice after removing null element is: [1 2 3 4] Conclusion

We executed this program of removing the nil elements from the slice using two examples. In the first method, we used for loop to remove nil elements, and in the second method; we used a filter method to remove the null values. Both examples give similar results.
