I have done a Spybot rootkit scan on my laptop and, apart from a whole list of files in the deep scan system, the quickscan list notes the following hidden files:

Windows folder:
C:\Windows\ õ@
C:\Windows\¼ú~
C:\Windows\äôa
C:\Windows\˜÷8BRs:

System folder:
C:\Windows\System32\€

Master Boot records:
Unknown MBRs: PhysicalDrive0

Can someone tell me whether they are of any concern please?

Thanks
Chris
