While I was online researching lessons for teaching my 7th graders, my computer became crazy. First it slowed down. Then, many windows began to open very fast. All my files on the computers changed to having .Ink at the end of the file name. example; google chrome.Ink. When I click on it, it trys to open as Word 2010 but it just stops working. This is hapening to every file in my computer. Did I get a virus?
What do I do? Is my hard drive toasted?

Thanks for your help
