So I had this weird page show up on my computer with badges and and police info stating illegal activity on my computer (if arguing with fellow gamers is a crime then I suppose accurate). I scrolled down the page and I think it had some super neon green text about paying a fine of $300 dollars via a MoneyPack card to unlock my computer. When this site popped up, avast chimed in and told me it blocked something. Well my computer wasn't locked and is working completely fine and I had simply closed out of the site without incident. What happened?
Under the "Last pop-up message" tab in Avast it has this as the URL: insert the http nonsense here...alert.secutity3-80000193.com/LEND/US/close.ph...
And below it is says Infection: JS:Ransomware-C [Trj]
So to reiterate, what just happened? Should I be worried?
