I think something else is going on. Some history: My computer was working fine a month ago. Then I started getting High Memory Use warnings when I was on internet explorer. When the low space on C drive alerts started coming up a few days ago, I deleted unused programs and temp files, and I was able to free up some space. However, it is now gone. Last night I was able to use disc cleanup and get 1%. Today, that is gone, too, and I haven't even used my computer. (I've already cleaned up restore points.) I'm a very low-level user and don't have much left to get rid of. I don't have any music, but I could move my pictures to an external drive. Again, though, I haven't made many changes in the last month. It just seems like something is draining the space. My full scan says there aren't any viruses, though, but it sure seems like there is.
