While that sounds a little shady on its own, it gets even worse: Security experts say the software, called Superfish, can open up a nice big door that lets hackers intercept your data. Lenovo said in a Thursday statement that it stopped pre-loading Superfish on laptops last month, and it won’t do so again in the future. Now, Lenovo is going a step further: It just [posted instructions](http://time.com/wp-content/uploads/2015/02/remove-superfish-instructions.pdf "undefined") for Lenovo owners to tell if they have Superfish and, if they do, how to erase it. That’s a significant backtrack for Lenovo: Earlier Thursday, the company [said](http://time.com/3714821/lenovo-malware/ "undefined") it could not “find any evidence to substantiate security concerns” over Superfish. Security experts, however, disagreed. They say the problem with Superfish is that it’s able to scan your Internet activity even when you’re on encrypted sites by spoofing a website’s security certificate. Hackers can take advantage of that fake certificate process to steal your data while it’s in transit. If you’ve got a Lenovo computer, it’s a good idea to follow [these instructions](http://time.com/wp-content/uploads/2015/02/remove-superfish-instructions.pdf "undefined") to see if you have Superfish and get rid of it. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3715937/lenovo-superfish/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3715937/lenovo-superfish/"},"headline":"Here's How to Remove Dangerous 'Superfish' Software From Your Computer","datePublished":"2015-02-19T23:18:03.000Z","dateModified":"2026-04-13T08:04:27.896Z","description":"It could make Lenovo users more vulnerable to hackers","url":"https://time.com/3715937/lenovo-superfish/","keywords":["Tech","Security"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd3f2fe5cc86f796b/69878029e20a871c10a85341/458888624.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alex Fitzpatrick","jobTitle":null,"url":"https://time.com/author/alex-fitzpatrick/"}],"articleSection":"Business","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd3f2fe5cc86f796b/69878029e20a871c10a85341/458888624.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Inside Lenovo Group Ltd.'s Headquarters And Flagship Store","caption":"Inside Lenovo Group Ltd.'s Headquarters And Flagship Store","creditText":"Bloomberg—Bloomberg via Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/business/","name":"Business"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/time-section-tech/","name":"Tech"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3715937/lenovo-superfish/","name":"Here's How to Remove Dangerous 'Superfish' Software From Your Computer"}}]}] ```
