RizeZone Technology Tech name Andy Software maintenance and Repair Scam India Internet

I was trying to order Norton Security and a pop-up message came up and said a technician will be calling you.  At first, I thought I was talking to a Norton Security Technician, when I was told the company's name is RizeZone. I still thought it was a contractor that Norton was using for security maintenance.  The tech's name is Andy and he told me that for $199.00 he could clean my computer and I would not have any more problems with computer viruses for the life of the computer and that included having Norton Security for 1 year.  He asked for access to my computer, which I gave him foolishly.  Once in my computer he told and showed me all these suppose viruses.  He told that my internet was not secure and I told him it was.  While he was talking I looked the company up on my smart phone and saw the 5 scam notes.  I immediately booted him off my computer and he asked me why.  I told him about the scam data and he put his supervisor on the phone who tried to tell that all companies get bad publicity.  I told him I needed to do some research and I would call back.  I contacted Norton and was able to download their security software for $49.95.  I don't know if this company is legal but I didn't feel comfortable with how they can chat with you as if they are another company.  I wonder if Norton realizes what they are doing.
