what is Windows Warning Error?
I left my home with computer on, for about 4 hours. I came home to find this warning box on screen Windows Warning Error. The page was locked and I had to force quit. The browser was Tubeblog2.com. There a warning that my iMac had a virus.I was able to quit page and began update that was available. So iMac seems ok but I am still worried. Any comments?
iMac (21.5-inch, Late 2013), iOS 8.3
