What is Superfish?</h2>
Superfish is a piece of software that <a href="http://news.lenovo.com/article_display.cfm?article_id=1929">Lenovo has admitted to pre-installing</a> on many of its laptops to "enhance the shopping experience" of its users. However, the <a href="https://www.us-cert.gov/ncas/alerts/TA15-051A">U.S. Computer Emergency Readiness Team</a> calls Superfish a "man-in-the-middle attack" because of how it "intercepts users' web traffic to provide targeted advertisements."</div>

Superfish snoops in on your web browsing and secretly slips ads into webpages. But the really dangerous part is that it's pre-installed with root certificate authority, which allows it to impersonate any server's security certificate.<br /><br />If this certificate is compromised by hackers, you could be tricked into logging in to a fake website and giving hackers your password. Because of Superfish, any of your accounts including encrypted bank accounts could be easily compromised.<br />

Will restoring from a backup help?</h2>
<div style="text-align: left;">
<br /></div>
<div style="text-align: left;">
Superfish has been pre-installed by Lenovo. Therefore, restoring your computer to factory condition from either a backup partition or a backup DVD will not solve the problem if Superfish is also part of your backup. Superfish would only be reinstalled, too.</div>
<div style="text-align: left;">
<br /></div>
<div style="text-align: left;">
So if you ever use a backup to restore your system, you may need to again remove Superfish and its root security certificate from your system.</div>
