Cyber threats targeting Android smartphone users in India are increasing as malware and adware pose risks to devices used for UPI payments, online banking and storage of personal data. Experts advise that timely identification of warning signs, review of settings and adoption of trusted security measures can reduce exposure to such risks.
Phone performance issues as warning signs
Sudden slowing of the device, frequent hanging or crashing, and unexplained overheating may indicate the presence of malware. Rapid battery drain, unknown pop-up advertisements and abnormal data consumption are also signs of potential infection. Even minor software irregularities can signal larger risks, requiring immediate review of installed applications and data usage through phone settings.
Monitoring installed apps and permissions
Users should review all installed applications through the Settings > Apps menu. Any unfamiliar or unusually named application should be treated with caution, as malware may disguise itself as a basic tool or flashlight app. Verifying the credibility of an application by searching its name online is recommended.
Through the Permission Manager, users can check which applications have access to the camera, microphone or messages. If a basic application requests such access without clear reason, it should be removed immediately.
Checking data usage and security tools
Under Settings > Network & Internet > Data Usage, users can identify applications consuming high amounts of data. Pop-up advertisements appearing without internet usage may indicate adware. Security applications should be downloaded only from trusted sources, and Google Play Protect should remain enabled. Unverified or third-party security applications may themselves pose risks.
Immediate action and preventive steps
If a device begins sending messages automatically or a banking application stops functioning, users should remove suspicious applications, change passwords and install software updates without delay. If problems continue, backing up data and performing a factory reset is the safest measure.
The risk of malware and adware remains present on Android devices. Regularly reviewing applications, permissions and data usage, installing trusted applications, avoiding unknown links and keeping software updated are essential measures for device security.
