I've been having a problem with my computer recently. Upon startup, I always get a window popping up titled "Data Execution Prevention - Microsoft Windows," which says "To help your computer, Windows has closed this program." The program closed is "WMI." When I click close message, a window saying WMI pops up saying "WMI encountered a problem and needed to close." When I click don't send, the first window ("Data Execution Prevention") pops back up again, so on, and so forth. Also, I noticed that my disk was almost completely full about a week ago, so I deleted about 11 GB worth of memory and checked it again today and saw that my disk was COMPLETELY full (not even 1 KB left). I don't know if I have a virus, or if something else is going on. Can somebody please help or offer some suggestions? Any help would be greatly appreciated.
