How to find out if Superfish infected your computer – and what to do about it

hackers-hacking-2

If you follow anything having to do with tech on the Internet, you have undoubtedly read something about Superfish in the past 24 hours. In a nutshell, Lenovo sold tons of computers with software called Superfish Visual Discovery pre-installed. Lenovo has been selling computers preloaded with Superfish for the past two years, and the software is supposed to help serve alternative, image-heavy ads in Google search results.

As it turns out, however, Superfish is a pretty frightening piece of adware.

Password management software maker LastPass explained Superfish quite well in a recent blog post:

It was discovered that the Superfish software was installing its own self-signed Root Certificate Authority so that the Superfish software always appears as a trusted party. The Superfish software would have the ability to then intercept supposedly-secure communications to websites via a man-in-the-middle attack. Researchers also confirmed that hackers on the same network, like an open WiFi hotspot at a coffee shop, can exploit Superfish to steal things like your banking login details or to read your emails.

Isn’t that great? You go out of your way to be safe while browsing the Internet and you’ve installed all sorts of protection against malware and adware, but Lenovo beats you to the punch by pre-installing adware on your PC.

Luckily, LastPass went beyond simply explaining what Superfish is, and the company created a tool that will instantly inform you if your computer is infected with Superfish.

It couldn’t be easier to use. Simply visit this page on the LastPass website and you’ll see a message at the top of the screen informing you of whether or not your computer is infected.

If you see this message, you’re good to go:
