Well, it was very weird. I used scan disk for looking for erros in disk, and none. Also defrag, and it told nme that I had used more than 9 Gb (when all I found were 2 Gb).
So finally here’s the error: one of the folders was using more than 6 Gb!!!
It’s C:\Documents and Settings\user\temp_avast_4\
(Before I had look at the size of C:\Documents and Settings\ and it was 0,2 Gb)
Really I don’t know why, this folder had a lot of files and it had that size. I’ve used Avast for a year or so, and it has never used so many bytes. And I’ve cleaned some viruses in my PC (the one that has had this problem with disk space ain’t mine).
So, RejZorR and whocares: thanks both of you for your help!!!
