The Advanced Calendar program from MEIXIAN XIE is advertised to display more convenient calendar updates from Google and your system on your desktop. The layout of the Advanced Calendar is a transparent window in the bottom right corner of your desktop and can be operated from an icon in your tray area. At first look, the Advanced Calendar program may appear very useful but you may want to know that Advanced Calendar is supported by advertisers. They can use Advanced Calendar to inject advertisements in your browser, and you may see words made bold with links to sponsored content, pop-up windows, coupons, and discounts. Therefore, Advanced Calendar is deemed as a Potentially Unwanted Program (PUP) that may provide you with exciting calendar features but will load a number of ads in your Internet browser to earn affiliate revenue. The Advanced Calendar program may edit your Windows registry to start with your OS and utilize a background process to show ads. Additionally, the Advanced Calendar program would use tracking cookies, record your search terms on Google and read your bookmarks to display tailor-suited advertisements. Advanced Calendar may show pop-under windows and promote software like Max Computer Cleaner and DropIntoDeals that would load more commercials into your Internet browser. Also, the Advanced Calendar program may ask to access your Facebook, and Google Plus accounts to add significant events and may post promotional materials on your feed. You may want to deny the access of Advanced Calendar to your social profiles and use a trusted anti-spyware instrument to remove it from your system.
