I know this probably belongs more on the macrumors website, but I was hoping someone could answer me here as people here are kinder. For the past few months my Macbook Pro Core 2 Duo 2.33ghz has seemed sluggish and been making a noise like it's busy when doing very basic tasks (typing in Microsoft Word, browsing the web, even sometimes just moving the mouse, and so on). When I watch a streaming video it makes an even worse clicking like sound. I thought maybe it was because I only had around 3gb of space left on my hard drive so I freed up some space and have 34 gb now and it's still making the noise. A couple of days ago the Norton Anti-Virus program said that I have been infected by the downloader. It's odd though because my computer has been this way for months so why would it only recognize the virus now. If anyone has any advice other than taking it to the genius bar, I'd appreciate it.
