I was writing an email an ad from McAfee popped up on my screen saying an uninvited website was trying to access my computer. It gave me an option to block access. I chose the option. Then I couldn’t access the internet. I called customer service after searching 30 minutes online from my phone for a phone #. They offered to resolve the problem if I’d renew my subscription for $75. I may have a subscription several years ago as a package when I purchased the computer. After I uninstalled their program from my computer I miraculously was able to access the internet again.
