Even trusted apps can infect your PC with malware now

Recent supply-chain attacks are increasingly targeting well-known software such as CCleaner, Steam games, and Notepad++, allowing hackers to distribute malware through legitimate updates. The introduction of artificial intelligence has accelerated the frequency and sophistication of these attacks, with hackers compromising developers or exploiting third-party tools to inject malicious code. Notepad++ was specifically affected by a supply-chain attack where a compromised third-party tool led to the distribution of tainted software. Attackers use various strategies, including hacking developers' credentials, purchasing access, or compromising tools relied upon by developers. Antivirus software is crucial for protecting users from malware, even from trusted sources, as modern solutions have minimal impact on system performance.

Free Antivirus for Android: Best Apps to Protect Your Smartphone

Smartphones are integral to daily life, storing emails, banking apps, and social media. The Android operating system is vulnerable to threats like viruses and ransomware. Free Android antivirus tools offer basic protection but have limitations compared to paid versions. Free antivirus solutions focus on malware scanning and threat detection. Bitdefender Mobile Security (Free Version) provides lightweight background operation, real-time scanning, and web protection but lacks anti-theft and VPN features. Norton Mobile Security (Free Tier) offers essential malware scanning, with advanced features available in premium subscriptions. Avast Mobile Security (Free) includes virus scanning, malware protection, and anti-theft tools, allowing users to lock apps and protect against malicious websites. AVG AntiVirus (Free) offers virus, malware, and spyware scanning, real-time updates, and a "Photo Vault" for securing images. Kaspersky Mobile Security (Free) provides basic virus protection and ranks high in malware detection, with additional features available in paid plans. Free antivirus tools detect malware and monitor real-time system activity, alerting users to phishing sites. They may scan files transferred via USB or Bluetooth and offer limited VPN services. Limitations of free antivirus include the absence of advanced features like unlimited VPN, application locking, and anti-theft capabilities. Many rely on ads for revenue, which can disrupt user experience. Choosing the right antivirus depends on usage habits and security concerns. Running multiple antivirus apps can cause conflicts and hinder performance. Upgrading to premium versions may be necessary for comprehensive protection, especially for sensitive tasks. User behavior is crucial for security; regularly updating the OS and applications, using strong passwords, and considering two-factor authentication can enhance protection. Free antivirus apps offer core threat protection but lack advanced features. Most are lightweight, with minimal impact on performance. Regular scans are recommended, and reputable sources should be used for downloads. Free antivirus apps can warn about phishing attempts but cannot eliminate the risk entirely. A built-in VPN is not essential for basic protection but is advisable for public Wi-Fi use.

What Is a Crypto Miner Virus?

A crypto miner virus, or cryptojacking malware, secretly uses a device’s CPU or GPU to mine cryptocurrency for an attacker, leading to increased electricity costs and potential hardware damage for the victim. It typically infects devices through phishing emails, pirated software, compromised websites, and malicious browser extensions. Monero is the preferred cryptocurrency for mining due to its efficiency on standard CPUs and privacy features. Signs of infection include overheating, high CPU usage, and increased electricity bills. Detection involves monitoring system performance and running antivirus scans. Prevention includes using antivirus software, keeping systems updated, and avoiding pirated software. Notable incidents include attacks on a European water utility and the Los Angeles Times website.

Avast Antivirus in 2026: Still Worth Paying For on Windows and Mac?

Ransomware is evolving, and many users in the United States continue to invest in Avast Antivirus as of 2026. Avast, now part of Gen Digital, has shifted from a traditional free antivirus to a comprehensive consumer security suite, which includes three tiers: Avast Free Antivirus, Avast Premium Security, and Avast One. The product lineup features a core antivirus engine, ransomware and phishing protection, a firewall, Wi-Fi inspector, built-in VPN, and performance cleanup tools. Avast's core antivirus engine provides real-time file scanning and web/email shields, consistently ranking high in independent lab tests for malware protection. The ransomware shield protects sensitive folders from unauthorized encryption, while the firewall and Wi-Fi inspector are available in paid tiers. The built-in VPN is designed for safer public Wi-Fi use, and performance tools aim to optimize system efficiency. Pricing for Avast products in the US varies, with a free tier supported by upsell prompts for premium features, Premium Security typically offered as an annual subscription, and Avast One marketed as a higher-value bundle. Renewal pricing often increases significantly after the first year, leading to user complaints. Microsoft Defender is now effective enough that many experts believe average users may not need third-party antivirus software, but Avast justifies its subscription by offering stronger web protection, more control over app permissions, and additional non-security features. User feedback highlights strong protection but frequent upsell prompts, performance issues on low-end machines, and concerns over past data collection practices. Avast is seen as valuable for households with mixed tech literacy, remote workers, students on older hardware, and users seeking basic privacy protections.

Not a virus: What it means and why antivirus flags it

The term “not a virus” is used by antivirus software to indicate that a file does not match known malware signatures but still triggers a detection. This means the file is not automatically blocked or confirmed as a threat; the alert highlights something unusual, leaving the decision to the user. Alerts typically arise when software exhibits behavior associated with increased risk, despite lacking clear evidence of malicious intent. Malware is specifically designed to inflict harm, while files labeled “not a virus” may perform actions that raise security concerns but are not classified as harmful. Antivirus programs identify threats through signature detection and heuristic behavior-based detection. Legitimate programs, such as system utilities, download managers, and game cheats, can inadvertently trigger “not a virus” alerts. Common types of detections include adware, riskware, and potentially unwanted applications (PUA). The primary security risk of “not a virus” files is exposure rather than direct attacks, and privacy concerns often arise from data collection by these programs. If an antivirus detects “not a virus,” users should identify the file, review recent changes, compare detections, and decide whether to keep or remove it. To reduce unwanted alerts, users should download from official sources, use custom installation options, and remove unused software.
