I have an Asus laptop. I don't know much about them. I can get on my internet fine, use all my functions fine. The problem is when I want or need to restart the laptop. I hit restart and after a few seconds I get a black and white line screen and have have to power it off. Then it will start fine. I think it is a virus since I get a full page ad on memorycontrol.biz. It says call this number to fix the computer and can only get rid of ad by shutting down. Is there any fix for this. Have windows defender and no virus or maleware found. What to do What to do. Asus 64 bit laptop, core i5
