A food delivery is tracked on it, a UPI payment is made during lunch and a work document is downloaded before a meeting. Then a familiar-looking message arrives: \u201cYour parcel could not be delivered. Update the details here.\u201d One tap later, a suspicious app asks for access to SMS messages and notifications.<\/span><\/p><p><span style=\"font-weight: 400\">This is where <\/span><span style=\"font-weight: 400\">mobile antivirus<\/span><span style=\"font-weight: 400\"> can make a difference. Smartphones now hold banking credentials, passwords, private photos and access to critical accounts, making them valuable targets for cybercriminals. While built-in security features provide an important layer of defence, they may not cover every threat. Malicious apps, phishing links, spyware and banking malware can still exploit unsafe downloads or risky behaviour.<\/span><\/p><p><span style=\"font-weight: 400\">So, does every smartphone really need <\/span><span style=\"font-weight: 400\">antivirus for mobile<\/span><span style=\"font-weight: 400\">? The answer depends on how the device is used, what risks it faces and how effectively its existing security features are configured.<\/span><\/p><h2><b>Why Mobile Security Matters<\/b><\/h2><p><span style=\"font-weight: 400\">Smartphones have become attractive targets because they combine sensitive information with constant connectivity.<\/span><\/p><p><span style=\"font-weight: 400\">A compromised phone can expose:<\/span><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Banking and payment credentials<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">OTPs and notification content<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Passwords and saved browser data<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Personal photographs and documents<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Contacts and messages<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Location and device information<\/span><\/li><\/ul><p><span style=\"font-weight: 400\">CERT-In continues to publish warnings about Android vulnerabilities, malicious applications and social engineering campaigns targeting mobile users. In May 2026, for example, CERT-In reported a high-severity Android vulnerability that could potentially allow remote code execution on affected devices.<\/span><\/p><p><span style=\"font-weight: 400\">The risk is therefore not limited to downloading an obviously suspicious app. Unpatched software, excessive permissions and deceptive links can all create opportunities for attackers.<\/span><\/p><h2><b>What Can Go Wrong Without Mobile Antivirus?<\/b><\/h2><p><span style=\"font-weight: 400\">Not every smartphone user needs the same level of protection. However, certain behaviours increase exposure considerably.<\/span><\/p><table><tbody><tr><td><p><b>Risky behaviour<\/b><\/p><\/td><td><p><b>Potential consequence<\/b><\/p><\/td><\/tr><tr><td><p><span style=\"font-weight: 400\">Installing APKs from messaging apps<\/span><\/p><\/td><td><p><span style=\"font-weight: 400\">Malware infection<\/span><\/p><\/td><\/tr><tr><td><p><span style=\"font-weight: 400\">Granting unnecessary permissions<\/span><\/p><\/td><td><p><span style=\"font-weight: 400\">Data or device access<\/span><\/p><\/td><\/tr><tr><td><p><span style=\"font-weight: 400\">Clicking unknown links<\/span><\/p><\/td><td><p><span style=\"font-weight: 400\">Phishing or malware<\/span><\/p><\/td><\/tr><tr><td><p><span style=\"font-weight: 400\">Using outdated software<\/span><\/p><\/td><td><p><span style=\"font-weight: 400\">Exploitation of vulnerabilities<\/span><\/p><\/td><\/tr><tr><td><p><span style=\"font-weight: 400\">Installing unofficial apps<\/span><\/p><\/td><td><p><span style=\"font-weight: 400\">Spyware or banking malware<\/span><\/p><\/td><\/tr><tr><td><p><span style=\"font-weight: 400\">Ignoring security warnings<\/span><\/p><\/td><td><p><span style=\"font-weight: 400\">Increased exposure to threats<\/span><\/p><\/td><\/tr><\/tbody><\/table><p><span style=\"font-weight: 400\">Someone who downloads apps exclusively from trusted stores, keeps the phone updated and avoids suspicious links already has several important safeguards in place.<\/span><\/p><p><span style=\"font-weight: 400\">However, those safeguards do not eliminate every risk.<\/span><\/p><h2><b>Common Mobile Threats to Watch<\/b><\/h2><h3><b>Malicious Apps<\/b><\/h3><p><span style=\"font-weight: 400\">Malware can disguise itself as a PDF reader, game, utility tool or government application. Once installed, it may request access to SMS, notifications, accessibility services or other sensitive features.<\/span><\/p><p><span style=\"font-weight: 400\">Some mobile malware is specifically designed to intercept OTPs, steal credentials or monitor activity.<\/span><\/p><h3><b>Phishing<\/b><\/h3><p><span style=\"font-weight: 400\">A fake banking, shopping or payment website can look almost identical to the real service. Once credentials are entered, the information goes directly to the attacker.<\/span><\/p><p><span style=\"font-weight: 400\">This is why <\/span><span style=\"font-weight: 400\">phishing protection<\/span><span style=\"font-weight: 400\"> remains important even when a phone has strong built-in app security.<\/span><\/p><h3><b>Banking Malware<\/b><\/h3><p><span style=\"font-weight: 400\">Banking malware can overlay fake login screens on genuine financial applications or monitor device activity. The objective is often straightforward: capture credentials and facilitate financial theft.<\/span><\/p><h3><b>Spyware<\/b><\/h3><p><span style=\"font-weight: 400\"><a href=\"https:\/\/www.quickheal.co.in\/knowledge-centre\/computer-protection-from-keyloggers-and-spyware\/?srsltid=AfmBOoqY5zt3xATXzZjmxSM0zMA4CHJdLgAOkLnVhBQfD_3fwNFnderS\">Spyware<\/a> can secretly monitor activity, collect personal information or capture sensitive data. It can be particularly difficult to identify because the device may continue functioning normally.<\/span><\/p><h3><b>Ransomware<\/b><\/h3><p><span style=\"font-weight: 400\">Although less common on phones than on PCs, mobile ransomware can lock files or devices and demand payment for access.<\/span><\/p><h2><b>Real-World Example: A Malicious APK Can Empty a Bank Account<\/b><\/h2><p><span style=\"font-weight: 400\">The threat is not hypothetical.<\/span><\/p><p><span style=\"font-weight: 400\">In May 2026, a 56-year-old teacher in Pune reportedly lost \u20b99.4 lakh after receiving a malicious APK disguised as a pension-related document. The file arrived from an unidentified number and was installed on the victim&#8217;s phone.<\/span><\/p><p><span style=\"font-weight: 400\">CERT-In has also warned about an Android malware campaign impersonating RTO and e-Challan notifications. Reported malicious files included names such as &#8220;RTO Challan.apk&#8221; and &#8220;MParivahan.apk&#8221;. Once installed, the malware could steal sensitive financial information and facilitate unauthorised transactions.\u00a0<\/span><\/p><p><span style=\"font-weight: 400\">These incidents highlight an important point: the threat often begins with <\/span><span style=\"font-weight: 400\">social engineering,<\/span><span style=\"font-weight: 400\"> not sophisticated hacking.<\/span><\/p><h2><b>Is Built-In Phone Security Enough?<\/b><\/h2><p><span style=\"font-weight: 400\">Modern smartphones already include several useful security features. These may include app screening, permission controls, secure browsing warnings, device encryption and automatic security updates.<\/span><\/p><p><span style=\"font-weight: 400\">They provide a strong baseline, particularly when users keep the operating system updated and download applications through official channels.<\/span><\/p><p><span style=\"font-weight: 400\">However, built-in security does not mean a device is completely protected.<\/span><\/p><p><span style=\"font-weight: 400\">Consider a user who receives a convincing WhatsApp message containing an APK. If the user manually downloads and installs the file while approving requested permissions, the attack is partly enabled by user action.<\/span><\/p><p><span style=\"font-weight: 400\">A layered approach can therefore be more effective.<\/span><\/p><h2><b>When Does Mobile Antivirus Make Sense?<\/b><\/h2><p><span style=\"font-weight: 400\">A <\/span><span style=\"font-weight: 400\">mobile antivirus<\/span><span style=\"font-weight: 400\"> can be particularly useful for people whose digital behaviour creates greater exposure.<\/span><\/p><p><span style=\"font-weight: 400\">It may be worth considering when a user:<\/span><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Frequently downloads files or applications.<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Uses the phone for banking and financial transactions.<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Receives work documents from multiple sources.<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Frequently uses public networks.<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight:

style=\"font-weight: 400\"><span style=\"font-weight: 400\">Uses Android devices with extensive app permissions.<\/span><\/li><\/ul><p><span style=\"font-weight: 400\">For users with relatively cautious habits, built-in security combined with regular updates may provide a reasonable baseline. <\/span><span style=\"font-weight: 400\">Antivirus for mobile<\/span><span style=\"font-weight: 400\"> adds another defensive layer rather than replacing those existing protections.<\/span><\/p><h2><b>How to Improve Smartphone Security<\/b><\/h2><p><span style=\"font-weight: 400\">Good
