1. Keys do not work in Any of the Internet Browsers. Even the on-screen keyboard does not help. 2. Every time I double click a file, A pop-up "Do you want xyz to make changes to the computer ?" is welcoming me! 3, I click on any of the icons in the task-bar and a new window is opening. For example, If I click on the firefox icon pinned at the bottom, Every instance I click it, a new window is opening 4. I am not able to open a folder by double click. I can only open it by right click and then Open 5. None of the keys and keyboard shorcuts seem to work. But that is not the problem with keyboard because, I am able to type words in Wordpad and Notepad I formatted my Windows 8 twice and still these problems are there. Even if I restart it, things work fine for 5 min and then the problem would be back. Can you please suggest me a solution / fix for this ? Please, that would be of great help. This is eating up the whole of my time.
