Something is running on my machine that is appending scripts to several file types including htm, html, js, asp and aspx. It is also dropping a file named "gifimg.php" in all my /images directories with a "base64_decode" string.

So far it has happened three times this month. It does not affect every file (of those types) on my machine.

Thank you very much for looking into this for me!
