I clicked on a website (I don’t remember what it was) and a new popup window ad appeared. A notification stated that I must contact engineers, the computer must not restart and it has been blocked. On the webpage it stated that my computer will restart in 5:05 minutes and my bank details are stolen.
Unfortunately, I got rid of the url and manually cleared the history as soon as I realized that it was a fake message. The keyword I searched was Instagram viewer; I now know that some of those viewer programs are unsafe.
