Superfish adware on Lenovo laptops
Lenovo preinstalled Superfish adware on Windows laptops from September 2014. Superfish injected shopping results into browsers and, worse, enabled others on the same Wi-Fi network to silently hijack the browser and capture anything typed into it — a serious security risk.
System Doctor is another example: posing as a legitimate anti-spyware program, it is malware that disables the user's security software, alters the browser, and diverts users to scam sites.
