phone-virus-hero

Smartphones play an integral part in our daily lives these days. They carry our personal information, financial details and our connection to the digital world. This makes them a gold mine for mobile data mining, phishing schemes and virus infections. 

Today, with more than 4 billion smartphone users in the world, your phone may be vulnerable to digital threats lurking on the internet, with Android users facing particularly high risk. So how do you know if your phone has a virus? Note any signs of suboptimal performance and work through the following guide on how to remove a virus from Android phones.

Can Android Phones Get Viruses?

Android phones can get a virus. As the popularity of smartphones exploded beyond that of computers as personal devices, hackers created new ways to infect and impair them. Unlike traditional viruses, which replicate themselves while running, mobile malware and viruses on mobile devices target weak points within your operating system for data mining, financial gain or network corruption.

Data-sharing capabilities are typically blocked between applications, but some apps have been scrutinized for speculations of mishandling data, making their users increasingly vulnerable to these types of attacks. On top of that, Android phones use open-source code, making them more customizable than other smartphones like iPhones, and therefore easier targets for hackers.

What Malware Can Do to Android Phones

The most common types of mobile viruses targeting Androids are adware, ransomware, spyware, trojan horses, and worms. The term “virus” is now widely used to describe almost any kind of security risk, but it is a specific form of malware. 

These harmful programs are designed to gain access to your Android phone, retrieve personal information, increase your data usage and damage the device. Some are even designed to trick you into providing all of that information yourself.

As for where they come from, the internet is a virus’s natural habitat. Legitimate applications, fake emails, infected attachments and many other digital landscapes are perfect grounds for viruses to hide.

Malware can damage an Android phone in many ways. It can affect battery performance, causing the device to overheat and leak data. They can also cause lag and performance issues, nonresponsiveness and random shut-downs. 

9 Signs Your Phone Has a Virus

While many viruses will simply limit the function of your phone, some are created to steal and remove data, transfer malware onto more devices or make unauthorized purchases. 

Because mobile malware can run dormant while you use your phone as usual, you may not recognize or know you have a virus immediately. Plus, some suboptimal performance issues are normal symptoms of wear on a phone. However, these symptoms can also be a sign of malicious malware at work.

These nine signs are an indication that your phone may have a virus:

  1. Excessive data usage: Undetected viruses running in the background of your phone may significantly increase data usage.
  2. Unauthorized charges: Some forms of trojans may drive up your phone bill with in-app purchases and text charges to premium accounts, which hackers can then collect on.
  3. Apps crashing: Apps may repeatedly crash if your mobile software is compromised. Before searching for a virus and assuming the worst, check that your storage isn’t full and you don’t have too many apps running simultaneously.
  4. Unusual search engines: Many people have a primary search engine they use for search queries. If your searches are being answered by new or unrecognizable search engines, this could be a sign that a virus has infected your phone.
  5. Pop-ups: While some pop-ups are a normal function of advertising while browsing the web, if your browser is closed and you’re experiencing increased pop-ups, you may be experiencing adware, a type of malware whose goal is data mining.
  6. Increased battery drain: You may experience an inexplicably quick drain on your battery with the increased use of your phone’s RAM if a virus is running in the background.
  7. Unrecognizable apps: When you see unrecognizable or fake apps that were mysteriously downloaded, they may be malware. Trojan horses can also attach themselves to legitimate applications and cause further damage.
  8. Overheating: Malware can consume RAM and CPU quickly, causing your phone to overheat. While occasional overheating may be normal, a chronic issue could be a signal that there’s something more dangerous afoot.
  9. Fraudulent linking: Malware may gather sensitive data and attempt to infect your contacts by sending dangerous links and attachments through texts, emails or social media messages.

How to Remove a Virus From an Android Phone

Android phones have more potential for customization. Because of its open-source code, Android devices are very easy to access and manipulate on a software level. This makes them vulnerable to malware attacks. Antivirus software is the most fail-safe way to protect your Android from viruses in the first place. However, there are four simple steps to remove a virus from an Android phone.

Step 1: Clear the Cache

The first item on your checklist is your browser. If you visited suspicious sites, some data will still be stored. Navigate to settings and select Apps & notifications. Next, find your browser of choice (in our example, we use Chrome). Go to its storage and select Clear cache.

Step 2: Reboot the Device

Press and hold the power button. When the dialogue box appears, choose reboot to safe mode. The term “safe mode” should appear in the corner of your screen after rebooting.

Step 3: Find Suspicious Apps

Open your settings. Select Apps. Tap See all apps and enter Installed apps in the dropdown menu. Manually review applications to find any suspicious downloads. Once identified, open the app information and uninstall or force close it. After this step, you can restart your phone like normal.

Step 4: Enable Play Protect

The most secure way to protect an Android against a virus is by installing an antivirus, but Play Protect can be used as a secondary protection measure. To enable this built-in software, enter the Google Play Store app and open the menu under your avatar. Choose to activate Play Protect so it can scan your device for security threats.

As a last resort, you can wipe your device and reset it to its factory settings. If this is your only choice, make sure all of your important documents, pictures and information are backed up to a secondary device or the cloud.

While security measures like Play Protect reduce the chances of malware infiltrating your Android, it’s best to use an antivirus so that your device is actively monitored and protected around the clock.

How to Check for Malware on Android Phone

Like vulnerability assessments for large infrastructure systems, it’s important to scan your smartphone for viruses regularly. While many viruses may make your phone act differently than normal, sophisticated viruses can often go virtually undetectable to the naked eye. Here’s how to see if your phone has a virus:

1. Run Regular Scans

Routine scans ensure there’s no unauthorized access or signs of malware on your phone. Installing an antivirus can be the difference between a fancy Android and a plastic brick. Make sure to routinely scan for any strange activity.

2. Check for Suspicious Apps

Go through your installed apps and confirm you recognize all of them. Sometimes, malware is embedded in the form of applications. Uninstall any apps you don’t recognize as quickly as possible before they cause any damage.

3. Examine Battery Usage

It’s fair to say that battery performance is a very common issue with modern smartphones. Just as it could be a sign of wear and tear, it can also indicate that malware is present. Examine your battery usage and see if it fits your screen time. 

4. Monitor Data Usage

Some malware manipulates the amount of data you use by running programs in the background that could bleed your data plan dry. Check your data usage for unexplainable activity and see if you can pinpoint which app it’s coming from.

5. Check Phone Performance

Go through your phone’s performance in settings and consider whether any strange behavior is a sign of an aging Android phone or malware. If this behavior has increased gradually over time, it’s likely the former; if it came on suddenly, do some further investigating.

If you have suspicions your phone may have a virus, removing it and investing in security systems should be a priority. While it may be necessary to wipe and restore your device if the virus is dangerous enough, there are simpler restoration techniques.

How to Remove a Virus From an iPhone

While the Android system is open-source, the iPhone operating system is fairly secure, making it less likely for malware to infiltrate an iPhone than an Android phone. But viruses can still break through closed-coded systems, especially on jailbroken iPhones. If your iPhone does manage to become infected by a virus, there are three steps you can take to remove the virus.

Step 1: Clear Your Browsing Data and History

First, select settings. Then choose your primary browser and clear its history and website data. If you regularly use any other browsers, repeat this process for them, too.

Step 2: Restore a Backup Version of Your Phone

Navigate to your phone’s settings, your Apple ID, and then the iCloud. Here, you should select Manage Storage, then Backups. Choose and restore the device to the most recent backup.

Step 3: Reset Your Phone to Its Factory Settings

This option should only be used as a last resort. Open your settings, choose General, find Transfer or Reset iPhone, and choose Erase All Content and Settings. Your phone will be reset to its factory settings.

Resetting your iPhone to its factory settings should always be the last remedy you try since you’ll lose access to any data or files that don’t have backups. Before this, follow the first two steps to remove a virus, install any iOS updates or download additional antivirus software for Mac and iOS devices to help protect your phone from hackers.

9 Tips to Protect Your Phone Against Viruses

As the first line of defense, antivirus software can protect your phone against malware. If all else fails, regularly backing up your phone will ensure you have a previous version to restore as a fail-safe. However, there are other steps you can take to protect your phone from a virus infection before resetting it becomes an option. 

Some viruses on cell phones are dormant until activated to infiltrate as much user data as possible before being detected. Antivirus software can protect your mobile devices against cyberattacks, and installing an Android VPN on your mobile device can offer additional protection from the instability of open-source codes.
