I have made some changes. First of all, I bought this one with my money, so I'm the only one touching it. My sister does NOT know how to use a computer probably and downloads shitty spyware programs like Morpheus and Bonzi Buddy. Secondly, I got better software, and soon so as to tackle the problem before it starts. McAfee was already installed, and I have AVG(as a backup), Spyware blaster, and a pop-up blocker. I should be safe as long as I run those programs on a consistent basis.
