How to remove malware from your Android phone

Many users may wonder, where can Android phones get infected with malware? In fact, the Android operating system runs on an open-source platform. This allows users to download files and applications from many different sources.

Additionally, applications and files from third-party sources are often unsafe for the Android system. Some third-party applications may be configured in ways that collect sensitive user data.

Mobile phones can become infected with malware from websites, third-party applications, or through interactions with suspicious text messages and emails. Some signs of malware infection include reduced performance and excessive data consumption.

What is malware?

Malware is software or mobile applications that are intentionally designed to harm users of computers, mobile devices, or software running on those computers/mobile devices.

Malware performs malicious acts, such as installing software without the user's consent or installing harmful software like viruses to disrupt the normal operation of a device and cause damage or steal sensitive information.

Mobile malware, which we often mistake for viruses, is largely malicious code disguised as legitimate software (Trojan horse), spyware, and computer worms.

According to Kaspersky (Russia), a well-known manufacturer and distributor of security software, most malware is designed to attack any widely used operating system that has numerous security vulnerabilities.

Common signs that your Android phone is infected with malware.

Here are some common signs that your Android phone is infected with malware.

The app frequently crashes:App crashes are unavoidable. But if multiple apps stop working unexpectedly or aren't functioning properly, there might be malware at play.

Increased data consumption:Applications infected with malware often run in the background, leading to increased data consumption. Users can force close or delete their stored data, but this is only a temporary solution as the malware will resume operation when the user reopens the application.

Spam messages are appearing:Malware can send links via email or text message to contacts to trick users into clicking on them. Hackers can also use these links to make purchases without the user's knowledge. Users may notice these suspicious transactions in their bank statements or receive receipts via email.

My phone's battery drains quickly:Malware-infected apps run in the background without the user's knowledge, consuming energy and reducing the phone's battery life.

The phone is overheating.Malware-infected applications running in the background will occupy a large amount of the phone's random access memory (RAM). This can make it difficult for the phone to perform other tasks simultaneously, causing the phone's temperature to rise rapidly.

Numerous advertisements appeared:When adware infiltrates a phone, it can take control of the user's browser, redirect users to other websites, install unauthorized extensions, and target users with various advertisements.

Google automatically logs out accounts:When Google detects malware on a phone, it will automatically delete the user's account and display a warning that says "You have been logged out for protection," along with suggestions for recovering the user's account.

Strange apps appeared:New apps suddenly appear on users' phones that they didn't install before.

How to remove malware from your Android phone

When there are signs that your Android phone is infected with malware, users should take the following steps to remove it.

Scan and remove malware using your Android phone's built-in security program.

Most Android phones nowadays come with a dedicated security program from the manufacturer. Users should check if their phone has such a program and perform a full system scan. After the scan, if the program detects malware, remove it immediately.

Use Android's Safe Mode to remove malware.

Users can also run "Safe Mode" to factory reset their Android phone and observe if their phone works normally. If not, you need to check all installed applications and uninstall any suspicious ones.

Clear your browser's cache and enable Google Play Protect.

Applications cache website data to make websites load faster when users revisit them. Clearing the cache might make websites load slightly slower when you visit them again. But with the cache clearing feature, users can also remove the connection between their phone and malicious websites.

Additionally, users should enable Google's Play Protect feature, which detects and blocks harmful apps. This feature scans all installed apps regardless of where they were downloaded.

The Play Protect feature also performs periodic security checks on the user's phone. When malware is detected, Play Protect will notify the user to uninstall the malicious applications or automatically delete them and notify the user afterward.

Update your phone to the latest operating system version.

Updating your phone to the latest operating system version will improve its functionality and compatibility with other apps and devices. Users will also get security patches and access to exciting new features. Typically, you'll receive notifications when new updates are available; if not, check for software updates in the settings menu.

Restore your phone to factory settings.

When users perform a factory reset on their phones, this action erases all settings, files, or applications, returning the device to its original state before it was unboxed and activated. However, users should only consider this method when all other steps fail to remove the malware and remember to create a data backup before performing a factory reset to avoid data loss.

Solutions to help protect your phone from being reinfected by malware.

Removing malware from your phone is a success; however, it's crucial to minimize the risk of reinfection. Therefore, users should avoid accessing suspicious websites, apps, and links from untrusted sources. Here are some solutions to help protect your phone from reinfection by malware:

Change your Google account password.

A user's Google account connects to several tools containing sensitive data, from the Drive storage service to word processing and spreadsheet tools (Docs and Sheets). If your Google account password falls into the wrong hands, your data could be stolen. Therefore, change your Google password immediately after dealing with malware.

Reset the network connection.

The network reset process essentially restores all network settings to their original default state on the mobile device, including mobile data and Wi-Fi settings. All Wi-Fi settings will be erased and restored to their initial state, including any virtual private network (VPN) the user has set up.

Resetting all custom network settings to their original values ​​is essentially a relatively effective way to fix several problems. For example, incorrectly specified settings will be removed, allowing the phone's network connection to function normally. If the user previously shared a connection with a suspicious device, the reset process will terminate the connection automatically in the future and prevent hackers from sending malware-containing files to the phone without permission.

Avoid suspicious apps and platforms.

Users frequently downloading third-party applications are highly likely to become infected with malware. Therefore, if necessary, carefully consider the applications and platforms you want to download, such as checking the reviews and ratings of those applications. If there are few or no reviews or ratings, you should not download them.

Some malware can disguise itself as legitimate apps or hide inside phone cleaners or optimizers. Modern Android phones offer many different ways to free up memory, so users don't need such apps.
