My mom went to prison right before the internet got popular. She got out ten years later. So in 2006 she got a computer with Windows XP. Constant infections. She was using IE and she pretty much clicked on everything. I was getting a few calls a week to come over and help.
It got to where I said that if she used IE I would charge her 35 per hour to fix it. She was convinced IE was the Internet. It cost her around a thousand dollars but now she uses Firefox. That was the first part.
Second part was email. NEVER CLICK ON EMAIL ATTACHMENTS unless are expecting it.
That took a few years to pound into her head.
Third: Install Ad-Bock plus/edge.
Forth: Install MSE. It is free and doesn’t constantly bug you or slow down your computer.
So eight years later she is now on Windows 7 and has only bugged me for hardware problems in the last few years.
