How to remove Advanced Calendar

What is Advanced Calendar

Advanced Calendar is a program developed by MEIXIAN XIE, designed to provide users with convenient calendar updates from Google and their local systems directly on their desktops. Initially, it may seem beneficial due to its transparent interface, which sits unobtrusively in the bottom corner of the screen. However, this application is classified as a Potentially Unwanted Program (PUP), primarily because it serves as a conduit for unwanted advertisements. Users may experience intrusive pop-ups, bolded links to sponsored content, and various promotional offers that disrupt their browsing experience. Additionally, Advanced Calendar often modifies system settings, such as the Windows registry, to ensure it launches with the operating system and continuously displays ads. It also collects user data, including search terms and bookmarks, to tailor advertisements, raising significant privacy concerns. Consequently, while it may offer some useful calendar features, its ad-driven nature and data collection practices make it a program many users seek to remove.

How Advanced Calendar infected your computer

Advanced Calendar typically infects computers through deceptive marketing tactics, often bundled with other software or distributed via misleading advertisements on websites. Once installed, it alters system settings to gain persistence, frequently modifying the Windows registry to ensure it runs at startup. The program injects advertisements into web browsers, leveraging tracking cookies to monitor user behavior and serve targeted ads based on browsing history. In some cases, it may request access to social media accounts, further increasing its reach and influence over user data. Users often unknowingly download Advanced Calendar while trying to install legitimate applications, highlighting the importance of careful software selection and vigilance during installations. To mitigate such risks, employing a reputable anti-malware solution is crucial for detecting and removing such potentially unwanted programs.
