Here's the situation:
While downloading some attachment from Yahoo mail (an Open Office document) saving the file fails.
At the same time I realized that when I tried to delete files (I thought maybe there were too many of them in the "download" dir. ) became impossible: Windows denies access.
At the same time creating or copying files is possible.
At the same time deleting files through CMD prompt (using "del" command) is possible.
I was able to restore the system to an earlier date which fixed the problem.
Then I went to download that file again. Saving fails. And deleting is lost again.
I read several links on the topic, but it seems to be different from what I have, suggesting using some utilities, or Administrator account etc.
ALL FILES are this way - I cannot delete ANYTHING anymore.
PS> I did run Avast full scan for viruses, and Spybot full scan for malware. Both came up negative.
