I have purchased a laptop before six months ago. This is very good Sony brands laptop. But last week I have problem in this laptop. When I start the laptop the Alt+Tab automatically start. I think is going to be due to virus. So I want to know is it virus problem or not? If yes then how can we fix this problem? I want to know suitable solution because I didn’t know much more about the system. Please response as soon as possible for you. Because this very irritating problem.
