some folders and files on my desktop have dissapeared. I do not know when but probably yesterday or so. I also have 0 mb of free space on C drive, and I am not sure whether or not all of the missing folders are in my recycle bin or not because I forget what each folder contains. I also checked for malware with malwarebytes with safe mode. Another wierd thing is that mse can't update and comes with an error message that says that it has expired.
