Some company was trying to sell me their security system. They said that the SSL certificate was expired on my laptop, which they showed me. They said that I wasn't protected. What are my options?
As a consumer, you do not need to worry about expired SSL certificates on YOUR machine. SSL certificates are owned by web servers and companies.
If this company contacted YOU to tell you something was wrong with your SSL certificates (and you do not own a web server), I can almost guarantee they are trying to scam you.
You must check sender's email address, if it is from the official source then they could be the real one,
But if the email address seems fake then it could be the phishing scam email. Generally hackers do this kind of stuffs to breach user's data.
Better to stay away and put this email in junk or trash.
