What's the worst scam you've fallen for (or gotten close to falling for)?

I went to buy Norton Antivirus. (This was... probably almost 25 years ago?) I went to https://symantic.com/. The correct domain name was https://symantec.com. ("e" vs "i").

https://symantic.com/ went to a page owned by... I think it was Avast. But the page was (in retrospect) very obviously meant to look like it was made by Symantec/Norton. It had images of cardboard boxes like software CDs used to come in and such, in exactly the Norton yellow/orange.

I went through their purchase funnel and installed Avast before I realized it wasn't Norton. As soon as I realized it, I immediately uninstalled it. I don't remember if I found any way to contact Avast, but I did call the credit card company and contested the charge. Avast contested the... con...test..ment...? I appealed and Avast gave up.

And I bought Norton.
