Then today, a complete folder disappeared along with some files in a shared folder. This could be some hacker's work but based on the files & folder that disappeared, they all have been shared (open, saved, clolse) between an XP machine and a Vista machine. This has not happened with all files that have been shared / used. Just a handful of files & an entire folder. Disappear means it no longer exist even on the machine is files were being saved to.
Never had an issue whem all machines were XP based. Added Vista and got this? Any thoughts? In a little bit of a panic mode here.
What could have caused this?
