Someone posted something similar to this on the forums before, but it was locked with no answer and it was not solved.
I have a Lenovo Flex 2 running Windows 10.
This evening after running a scan my Norton Security popped up to tell me that it found: cert8.db contains threat Adware.Superfishremove and that I needed to get a repair tool from the Lenovo Website, according to the Norton website, which I did.
I scanned my laptop with this tool, and it was clear of any threat, without removing anything.
Manual removal instructions are here, on the Norton website:
https://us.norton.com/security_response/writeup.jsp?docid=2015-022523-4531-99&tabid=3
And, on the Lenovo website:
https://support.lenovo.com/us/en/product_security/superfish_uninstall
I followed them, and there was nothing related to Superfish in my Add/Remove Programs, there was nothing labeled Superfish in Mozilla Firefox's Certificated Manager. I do not use Thunderbird.
I looked in Windows Certificates manager and there was nothing regarding Superfish in Trusted Roots Certificates (or any other certificates folder).
I went back to Norton Security to see where the file was that was flagged for Superfish and found that it resided in:
C:\Users\MyUserName\AppData\Roaming\Mozilla\Firefox\Profiles\zsuyyn3l.default in the file named Cert8, which is a database file. I opened the file with Notebook and could see the name Superfish, Inc. listed in the file several times, so I guess this is what it's picking up on.
This was detected by auto-protect, but I run a scan every day that my laptop is open and I've had this laptop for almost 2 years, so why is it just now picking this up if it originated sometime in 2015?
Can this file be deleted safely? The other person who posted a couple of years ago said that it just kept coming back.
Is this a false positive?
Thank you.
