You Are not Alone with Trade Exchange
Here are what some of the victims get the impression on Trade Exchange (Tradeexchange.com) pop-up:
Case 1: "Browsing using google chrome I get redirected to websites like tradeexchange.com randomly and websites telling me to call numbers to clear infection. It may be an hour or may be a few minutes into my browsing I don't know, seems independent of the site I'm currently on."
