Hey rodneyb!
I work for Ad Lightning, the company that got flagged here. We reached out to Malwarebytes and they confirmed our flag was a mistake, and they fixed it. Unfortunately, until folks update their software, our URL will still be flagged.
We actually work to fight malware and bad ads. Our clients are publishers like newspapers, video sites, local news, magazines, etc. They use us to stop those annoying "You've won an Amazon gift card!" redirects, and other malware stuffing. What probably happened is you were on one of those ordinary websites you visit, that company was a client of ours, and Malwarebytes flagged our script. Here's an article about us from GeekWire if you want to know we're legit!
Here's what Malwarebytes told us folks need to do in order to stop that flag:
Hope this helps! If you have any questions, feel free to email us!
Thanks,
Zoey
