Security researchers have discovered a number of Android apps that contain sophisticated malware.
The 29 apps, ranging from power management apps to horoscope apps, were infected by Trojan malware, which remotely controls the app after they gain access to the victim's phone, said We Live Security, a blog of the company IT company ESET.
After ESET informed Google about the problem, the malicious apps were removed from the Play Store.
However, it is believed to have been installed by almost 30,000 users.

Researchers have discovered a number of Android apps that contain sophisticated malware. The apps were removed from the Play Store but downloaded about 30,000 times
The Trojan has been found to affect a number of apps, including "Free Daily Horoscope" and "Power Manager" in the Play Store.
"Unlike the increasingly common malicious apps that rely solely on the identity of legitimate financial institutions and the display of fake login screens, these apps are a category of sophisticated mobile banking malware with complex features and a strong focus on stealth," said We Live Security in a blog post.
The researchers believe the malicious apps were created by a single attacker or a group.
The apps can intercept call logs, download apps, and bypass two-factor authentication to redirect text messaging.
You can do this by getting the HTML code of apps on your device and then inserting fake phishing forms into the apps.
This gives the victim the opportunity to "notice that something is wrong," said ESET.

In some cases, the apps will display an error message after the download stating that the app is not compatible with your device and has been removed.
However, the apps continue to download on the victim's device and hide in the background.
In some cases, they continue to function normally and display relevant information that would otherwise appear normal.
The main purpose of the malware is to dump a user's banking apps, get their credentials, and steal money.
However, ESET did not mention cases where the malware had achieved this.

The researchers said that the apps do not use "advanced tricks" to continue infecting the device so they can be easily removed.
Victims can simply uninstall them by navigating to Settings, then clicking General and clicking Application Manager / Apps, as ESET notes.
"We also recommend checking your bank account for suspicious transactions and changing the password and PIN code for Internet banking," the researchers said.
ESET also added that Android users should only download apps from Google Play to check how often they were downloaded and their ratings.
They recommend that users look at what permissions they grant to a particular app after it has been downloaded to their device.
