EX 3700 Extender - installed 7/19/18 and was told by tech to purchase Eqosoft firewall

I had a similar experience on 31 March 2020.   It took an hour for the whole scam to take place.   Fortunately, I suspected that something was wrong and did not fall for the scam of purchasing the firewall.  I have been feeling sick ever since.   It is hard to know what was taking place while he had direct access to my computer.   I have checked with Malwarebytes and other virus scanning software but am still scepticle about whether or not some trojan or other malware may have been installed during the session.   

I note that this seems to have been going on for quite sometime.   I note that there is a message with the product about only using NETGEAR support resources.   Perhaps this needs to be more prominently displayed for those of us who tend to search online for support when required.   Yes, I know that NETGEAR cannot be responsible for my lack of caution.   However, the problem seems to be an ongoing one.

The whole experience was very polished and seemed to be the real deal, hence the tendency to move ahead with the online assistance from this fake site.
