Computer issues

[Vipershark]

So yesterday morning my Dad logged onto the computer and absolutely everything on it was gone. He is working to get them back, but it's going kind of slowly, and he is on the computer practically 24/7 now, so I will not be on TSR much if at all for a while. We also cant download anything at the moment, so I cant get Skype back yet.

EDIT: If anyone who was on Skype has or can find any of the stuff I posted, please post it here, because I doubt I will be able to get it back.

I highly highly doubt everything is gone. you most likely got one of those rogue "security" programs that just hides all your files

in fact, i'm 99.9 percent sure that's the case.
just enable viewing hidden files and folders and then RUN MALWAREBYTES

tell you dad you know what to do
run malwarebytes, backup your files, and reformat

i can walk you through the entire process step by step if need be but you have to get your dad to let me help you first
