For a couple weeks now, something was taking up a 100% of my ram and i couldnt figure it out. I think it's a virus, but several scans by kaspersky and malwarebytes turned up empty. I know patience is key, but i have school in a week and need this gone as soon as possible. I have a Lenovo Y40 and am using windows 8.1. In short, there is something (I think is a virus), that is rapidly eating up my disk space.
