Yahoo! Anti-Spy

What is Yahoo! Anti-Spy?  (from Yahoo!)

Yahoo! Anti-Spy is the Yahoo! solution for detecting and removing spyware and adware on your computer. It scans your computer to find spyware and adware and lets you decide what to remove, what to quarantine, and what to ignore.


Yahoo! Anti-Spy is a software program developed by Yahoo!. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The primary executable is named ypsr.exe. The setup package generally installs about 33 files and is usually about 2.84 MB (2,982,940 bytes). Relative to the overall usage of users who have this installed on their PCs, most are running Windows 7 (SP1) and Windows XP. While about 75% of users of Yahoo! Anti-Spy come from the United States, it is also popular in India and Germany.
