Hello everyone We have a DSL modem hooked up via ethernet to an iMac then sharing the connection via WiFi to my mac mini. We get these popup boxes from "Windows" im sure its a virus but anyways we know that exe does not work on us. Code: Your browser is under the threat of infection. Windows requires your permission to install online protection tool. we have cleared caches on both computers used the dnscleaner on both and still have this popup if anyone can help thats great, thank you all so much!
