Android Phone with malicious apps

Come across an unfamiliar app on your Android phone or tablet and don’t know how it got there? While the Google Play Store takes security seriously, malicious apps disguised as legitimate ones can still slip through the cracks.

If you find a random app on your Android, the first step is to assess the situation. Is your phone also exhibiting strange behavior? Does it run slower than usual, crash frequently, or drain the battery abnormally fast? These could be red flags, indicating that the mystery app might be malware in disguise.

There are plenty of ways a random app can install on your Android, whether from a malicious link on a website or an app changing its icon. In rare cases, even an unknown Bluetooth device could be causing problems.

This guide will help you get rid of random apps installed on Android and show you how the best antivirus software can keep you safe.

    Apps and browsers store your online activities, and malicious software can use this to cause more harm. Clearing your browser and app cache on your Android device will help minimize the effects of malware.

    To clear app cache, head to Settings on your Android. Select Storage and choose Apps. Select an app. Tap Clear cache.

    Many Android owners use Google Chrome as their default browser, so you may also want to clear browser cache.

    Open Chrome and tap the three vertical dots in the upper-right corner. Select Settings, then Privacy and security. Select Clear browsing data. To just clear cache, uncheck Browsing history and Cookies and site data, then tap Clear data.

  3. Change your passwords

    If a random app appears on your Android and you’re seeing suspicious activity, chances are your Android has been infected with a virus or malware, and your online accounts and devices are at risk of being compromised.

    To help mitigate potential malware threats or hackers taking control of your accounts, change your passwords and use a strong password to stop suspicious activity. 

    Using password managers such as LastPass or 1Password for Android can help manage all your passwords in one place, create a complex, near-unbreakable master password and encrypt your information. 

    Changing passwords will stop hackers from trying to steal any sensitive information and your online accounts.

How does Android get malware?

There are numerous ways malware can infect your Android. From adware and Trojans to ransomware and spyware, hackers use all kinds of malware to loot your personal and financial data – and all it takes is a mistaken click on a dodgy website, malicious email attachment or suspicious app on the Play Store that has slipped through the cracks.

A popular method for hackers to infect mobile devices is through apps. There are plenty of examples of malware on Android apps, as it’s an easy way to trick potential victims into downloading legitimate-looking apps. The Google Play Store for Android users sees apps infested with malware make their way onto users’ devices (such as the FluHorse and Fleckpe Android malware).

What’s more, Android phones have easier access to third-party app stores. While some of these stores can be an excellent resource for those who need them, they can also be easier for threat actors to make their malicious apps available. Simply downloading these apps can infect your smartphone with malware.
