I have a laptop that's a few months under a year old. The account on this laptop that I'm currently using is my third or fourth account, because my old ones kept messing up. I use Google for everything (literally), and my dad said I keep getting spyware and viruses from infected sites that I click on from Google. It's not a huge problem - he just makes me a new account every time the current one goes crazy. But this account, which he just made a few days ago, has some problems unlike the kind I used to have. This time, whenever I've been on the Internet for a while, when I close my Internet window, a smaller window - like a popup - is behind it. But the window isn't the usual kind of ad popups you get - it's a random Google search. (For example, the most recent one was the results for Google shopping search for iPhone.) Also, when I go to Google on purpose an search something, most of the sites I click on redirect me to an unfamiliar site with more search results - it's not Google-based, and it's not usually the same search site. But this happens with sites I've been to before without that problem, like robinjones.com. (I googled it to find the right address for the site, but when I clicked it that redirect thing happened.) I didn't think twice about it until now, when the popup problem happened. This time the window was in YouTube on some random user and it was asking "Are you sure you wish to block this user?" I don't even have a YouTube account! It's like someone else is using my computer at the same time as me. Have I been hacked or something?

Your computer is full of malware by the sounds of it. I would install MBAM and run it in Safe Mode: Malwarebytes : Malwarebytes Anti-Malware is a free download that removes viruses and malware from your computer

Then I would ditch whatever AV you have and install and scan using MSE: http://www.microsoft.com/security/pc-security/mse.aspx
