What is Superfish?
Superfish is a piece of software that Lenovo has admitted to pre-installing on many of its laptops to "enhance the shopping experience" of its users. However, the U.S. Computer Emergency Readiness Team
calls Superfish a "man-in-the-middle attack" because of how it
"intercepts users' web traffic to provide targeted advertisements."
Why is Superfish so dangerous?
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.
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.

Will restoring from a backup help?
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.
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.
