Another that I haven't seen (or for a long while) "We found a spy cookie on your PC."
Considering the precautions I take having in Firefox, Cookie Monster add-on and in the Firefox settings I have the Do Not Trach setting enabled, I also don't accept 3rd party cookies and those that I do allow are cleared after the browser is shut down.
So I don't feel they present a risk to me, so this popup is scareware, so I followed the Resolve button (image1) to see what it showed and went (knowing full well what was going to happen.
It told me what these trackers do (I know that already) but it didn't show this supposed Spy Cookie on my PC that it found. I clicked the Continue button (image2)>
Here I got exactly what I expected the sales pitch (image3), no way would I pay for this so called protection (that I feel I have covered), not to mention I would never purchase anything promoted in this way scareware.
