Interpretation of the causes of problems

Many of the software, including Microsoft, use Windows's scheduled tasks to perform tasks that require scheduled operations, such as Windows Defender, Norton, Mcafee, Apple, Sogou, and so on. Windows Vista itself also has a number of planned tasks built into it. A scheduled task without cleanup after some software uninstall or files are deleted directly causes the Windows hint we see today to have no floppy disk. Windows actually prompts you not to find a file on the disk that is defined in the scheduled task, and then you cannot perform the related operation.

The problem with Jinshan poison PA and any anti-virus software is not necessarily linked, such as Papa get the user from the detection log to see the installation of Kaspersky will also appear this problem.
