NOT ANY, NONE, NEVER HAPPENS that some anonymous Good Samaritan company online is scanning everybody to keep them safe and detected something on your computer or device and is going to help you just because they are oh so good and kind.
It is a fairy tale story. They told you about a Goblin and they will slay it for you. Then you can ride a unicorn to the feast where you will become King.
If some anonymous popup says you have a virus it is from the evil troll what lives under the bridge, he's trying to lure you down there with gumdrops. Run little boy, run fast as you can and don't look back or that troll will eat you alive.
