| Verdict: | Malicious activity |
| Threats: | Adware is a form of malware that targets users with unwanted advertisements, often disrupting their browsing experience. It typically infiltrates systems through software bundling, malicious websites, or deceptive downloads. Once installed, it may track user activity, collect sensitive data, and display intrusive ads, including pop-ups or banners. Some advanced adware variants can bypass security measures and establish persistence on devices, making removal challenging. Additionally, adware can create vulnerabilities that other malware can exploit, posing a significant risk to user privacy and system security. |
