I thought you did it on purpose to indicate an invective.
Are you using Explorer, or some other browser, like Firefox?
Husband gets same message. I get it on Kindle. Only on Freerepublic and Lucianne.
Both of these sites are conducting a fundraising type of thing, if that’s a clue.
BUT...when you click on the “TAKE ACTION NOW” button it does nothing at all. Being on Kindle, I don’t think it’s a virus. There’s something Comcast or Xfinity is finding on these sites but it’s an all botched up thing as Xfinity arranges for free internet for the poor and cell phones for everybody as was a condition of the sale of NBC to them.
