I published an article of Lenovo Devices Cannot Be Trusted for Secure Work at http://goo.gl/ywaFSr. It describes a problem in Lenovo laptops sold between September 2014 and January 2015 that allows hackers to intercept encrypted communications from the laptops by snooping on wi-fi connections.
Lenovo-branded devices sold between September 2014 and January 2015 through consumer online and retail stores, like Best Buy and Amazon.com, are likely affected by the Superfish adware, which hijacks secure internet traffic.
Now you can test your computer within seconds to see if it is infected with Superfish. If you are using either Internet Explorer or Chrome, simply click on this link: https://filippo.io/Badfish.
NOTE: The test won’t work if you are using Firefox.
If you get a No, you’re good, if you get a Yes, go to the Lenovo web site at http://support.lenovo.com/us/en/product_security/superfish_uninstall to run the Automatic Removal Toot to remove the Superfish malware (malevolent softare) from your computer.
