Cyber threats targeting smartphones have evolved to include sophisticated malware and ransomware, with Android being particularly vulnerable to cyberattacks compared to iOS. Google recommends downloading apps only from the official Play Store, but some malicious applications can bypass these security measures. To protect Android devices from malware, investing in a reliable antivirus app is essential. Bitdefender Mobile Security is currently the top-rated Android antivirus app with a 4.7-star rating on Google Play, offering features like real-time web protection and app scanning. A free version is available, but a subscription is required for enhanced features. Sophos Intercept X for Mobile is a commendable free option with a 3.9-star rating, providing threat scanning and app protection. Other notable antivirus apps include Avast Security and Virus Cleaner, which has a 4.6-star rating and features a web shield and junk removal, and Malwarebytes Mobile Security, also rated 4.6 stars, known for its quick scans and digital footprint service. Norton360, with a 4.6-star rating, offers a comprehensive suite of features including antivirus scanning and a VPN. The best Android antivirus apps of 2025 include: - Bitdefender Mobile Security: Free, per year, 4.7 stars, 448K reviews - Sophos Intercept X: Free, 4.1 stars, 47.1K reviews - Avast: Ad-supported free, 4.6 stars, 7.34M reviews - Malwarebytes: Free, per year, 4.6 stars, 423K reviews - Norton360: Paid plans, 4.6 stars, 1.92M reviews The mobile malware landscape has reportedly increased by 151% since the beginning of 2025, with Google taking legal action against the BadBox 2.0 botnet targeting IoT devices, including Android. A new malware variant named ClickFix is also emerging, affecting macOS, Android, and iOS platforms. Relying solely on built-in protection and the Google Play Store is not advisable; a reputable antivirus app is recommended for additional security.

Malwarebytes, founded in 2004 by Marcin Kleczynski, is an independent cybersecurity company that provides effective malware protection globally. The Malwarebytes Premium Security suite includes antivirus, phishing and identity protection, and an unlimited VPN powered by Mullvad. Pricing for the one-year license for a single device is .99, while a five-device license costs .99, and a two-year plan is priced at .98. The Premium Security Ultimate plan offers full identity protection and credit monitoring for .99 for the first year, with renewal at 9.99. A limited free version is available that detects and removes existing threats but lacks real-time protection. The app features a straightforward design with a clear dashboard, prioritizing user experience. Malwarebytes focuses on efficient scanning of commonly infected areas, completing test scans in 13 minutes. However, it does not automatically scan removable drives and lacks a warning system for password-protected files. Independent lab testing is infrequent, but Malwarebytes has received an AVLab 'Product of the Year' award and demonstrated strong performance in MRG Effitas assessments. In practical tests, Malwarebytes effectively detected known malware but struggled with behavioral detection against custom ransomware. It includes anti-phishing features, initially blocking 16% of phishing sites, which improved to 62% with the BrowserGuard extension. The unlimited VPN offers encryption and privacy but has limitations in unblocking streaming services. The identity protection feature scans for breaches associated with user email addresses and Social Security Numbers for U.S. users.

All modern Windows PCs come with Microsoft Defender, a built-in antivirus solution. A tool called Defendnot can disable Microsoft Defender by tricking Windows into believing another antivirus is active. It uses an undocumented API to register a counterfeit antivirus, which leads to Microsoft Defender being automatically disabled without user notification. Defendnot creates a scheduled task for persistence and allows customization of the antivirus name. It is a successor to a previous project, No-Defender, which was removed due to copyright issues. Currently, Microsoft Defender flags Defendnot as a threat.

When a user downloads or shares a file via torrent, their IP address becomes visible to other participants in the network. The service IKnowWhatYouDownload aggregates this information, allowing users to search by IP address to uncover a list of torrents downloaded or shared from that specific address, along with corresponding dates and times of activity. This service can be used for legal matters, network monitoring, targeted advertising, and RedTeam operations. For example, Yandex Cloud provides a list of public addresses, and a specific IP address (84.252.128.118) was identified as having utilized torrents, allowing for the collection of related statistics on its torrent activity.

Infostealer malware has become a major cybersecurity threat, with around 25 million users targeted between early 2023 and the end of 2024. These malware variants capture sensitive information, including bank card details and passwords, with nearly 26 million devices affected during this period, resulting in over 2 million unique bank card details leaked. One in every 14 infections compromised bank card data, passwords, and second-factor authentication cookies. In 2024, infections increased significantly, with RisePro's share rising from 1.4% to 22.45% and Stealc from 2.65% to 13.33%. Redline remained the most prevalent infostealer, responsible for 34.36% of infections.

Over 9 million infections were tracked in 2024, with final counts expected to exceed those of 2023. To protect sensitive information, it is recommended to invest in robust antivirus software, use virtual cards for online transactions, set up transaction alerts and spending limits, avoid storing card details in browsers, use strong and unique passwords, and consider personal data removal services.
