There's also a Duplicate File Finder from Auslogics.

I was all set to remote in, but MOFF had freed up a lot of space with Ccleaner, and was happy with that for now.

But I WOULD like to know, as blue said, which anti-virus program you are using.

I'd still be happy to remote in and have a look around...you and I would be on chat so you and I would be able to communicate.

I call it 'the haunted computer' cause your cursor moves around the screen and it's not YOU using the mouse!

Again, I'd be happy to do a free inspection of your system...there might be something wacky there.

If nothing else, go to www.malwarebytes.com and download the free version. It heads straight for the nasties!
