so some days ago my computer suddenly began running very slowly and i noticed that something was taking up 20GB's of space, though i haven't installed anything. it happened a couple of times and today, malwarebytes has been blocking some ip from skype. I wasn't really sure what was going on so i figured i would just try reinstalling skype, but it won't let me delete anything, I'm getting "You need permission from SYSTEM to perform this action" and i'm not sure if that's normal. I'm probably not doing this right so if anyone could help that would be great Addition.txtFRST.txt
