Here’s What Actually Happens When Antivirus Software Scans Your PC

Interactions with antivirus software occur during installation and when issues arise, while the software operates quietly in the background. Modern antivirus solutions continuously monitor for threats using various detection methods, including real-time scanning, which actively scrutinizes files as they are downloaded or accessed. The signature database is essential for identifying malware by comparing files against known signatures, but it can only detect documented threats. Heuristic detection and behavioral analysis help catch unknown malware by evaluating suspicious characteristics and monitoring file actions during execution. Sandboxing allows suspicious files to run in a controlled environment, logging their behavior to determine if they are malicious. Quarantine neutralizes threats by locking files in a secure location, allowing users to review them before deletion. Full scans are resource-intensive and can slow down system performance, while real-time scanning is less demanding. Users can schedule scans during idle times, exclude trusted folders, or consider cloud-based solutions to mitigate performance impacts.

New Rokarolla Android Trojan Targets 217 Banking and Crypto Apps

Zimperium’s zLabs researchers have analyzed a newly identified Android banking trojan named Rokarolla, which targets 217 distinct banking and cryptocurrency applications. It is distributed through malicious websites that impersonate popular platforms like TikTok and Google Chrome, with one identified distribution point being hxxps://infocontablidades[.]it[.]com/. The malware uses a dropper disguised as Google Play Protect to install a second-stage payload and gain Accessibility Services access, allowing it to simulate user interactions and manipulate on-screen elements. Rokarolla downloads counterfeit HTML login pages for targeted applications and overlays them to capture user credentials, including sensitive card information. It can also deploy a fraudulent PIN entry screen, read and send SMS messages, intercept one-time codes from banks, and block incoming calls. The malware rewrites the clipboard, operates a keylogger and screen content logger, and scrapes WhatsApp contact data. It captures screenshots without alerting users and has a resilient command-and-control infrastructure with multiple fallback domains. No product flaws are exploited, and defenses against it include installing apps only from Google Play and being cautious with Accessibility Services. Zimperium’s Mobile Threat Defense and zDefend products can detect Rokarolla, and a list of indicators of compromise is available on their GitHub repository.

New Windows Zero‑Day Flaws Target Defender and BitLocker

A cybersecurity researcher known as “Nightmare Eclipse” has revealed two zero-day exploits threatening Windows systems: RoguePlanet and GreatXML. RoguePlanet targets Microsoft Defender, allowing attackers to execute privileged actions and gain SYSTEM-level access on Windows machines. It is a local privilege escalation vulnerability that remains effective on fully updated systems. GreatXML claims to bypass BitLocker disk encryption by manipulating the Windows Recovery Environment, potentially granting access to protected files. However, its effectiveness may be overstated, as it might require administrator-level access. Microsoft advises organizations to implement security updates, treat lost or accessible devices as high-risk, enforce stricter policies, and monitor threat intelligence to mitigate exposure to these vulnerabilities.

On this day: Microsoft’s 2016 Android‑Windows app port plan predicted today’s AI ecosystem

Microsoft has been working on bridging the gap between Android and Windows 10 for over a decade, initially encouraging developers to port applications and integrate notifications through Cortana. As of 2026, Microsoft's AI strategy continues to focus on cross-platform compatibility, evolving from earlier projects like Astoria and Cortana. Recently, Microsoft introduced a "request app" functionality in Windows 10 that allows users to suggest apps for the Windows Store directly from notifications on their Android smartphones. This feature was first identified by a Reddit user and directs users to a UserVoice page for app recommendations. Notification syncing between Android and Windows 10 is currently limited to Insider builds of 'Redstone', and the request feature has shown some inconsistencies.

Gemini 3.5 Flash lands on Google’s Android coding rankings, but it’s 3x the cost for slower performance

Google has released benchmark results for evaluating AI models in Android coding, revealing that the Gemini 3.5 Flash is the most resource-intensive model but ranks sixth overall. The benchmarks indicate that Gemini 3.5 Flash has higher latency and a 9% performance gap compared to its predecessor, Gemini 3.1 Pro Preview, despite being marketed as a faster alternative. In terms of cost, Gemini 3.5 Flash averages 355.9 tokens per benchmark run at approximately 7.1, while Gemini 3.1 Pro Preview uses only 73.3 tokens at about a third of that cost. The top-ranked models include GPT 5.5, GPT 5.4, and Gemini 3.1 Pro Preview, while Claude Opus 4.7 ranks fourth. The rankings feature both open-weight and closed-weight models, with the list remaining consistent since the last release, except for the removal of GPT 5.3 Codex.

Fake verification pages are stealing Steam accounts from players

Online gamers are being warned about a scam targeting Steam accounts through counterfeit FACEIT verification pages that look authentic. These fraudulent sites feature official branding and functional links, tricking users into entering their passwords. The scam is particularly aimed at FACEIT players, as it exploits the connection between FACEIT and Steam, where players link their accounts. The scam starts with a website mimicking an official FACEIT page, claiming to offer free identity verification. Scammers use lookalike URLs, such as faceit-discord.com and faceit-clubs-verify.com, to deceive users. The site may display subtle errors, like conflicting copyright dates, and encourages users to click a “Sign in through Steam” button, which leads to a fake login window designed to steal user credentials. To protect against this scam, users should verify the website address, be cautious of blurry QR codes, treat urgent messages as suspicious, navigate directly to official sites, and consider using tools like Malwarebytes Browser Guard. If users have already entered their details, they should change their Steam password, enable Steam Guard, and check for unauthorized activity. The scam's effectiveness lies in its convincing presentation and the use of Browser-in-the-Browser attacks, which manipulate the perceived address bar.
