Question about hard drive surface scan?

Don't download software you don't understand.

Is it possible that you have a refurbished hard drive? Or someone else has used your system?

When you surf the web the pictures on websites need to download to your computer for you to view them. They are usually kept in temporary files that are deleted at some point depending on your browser settings. Those files can be found by recovery software because Windows doesn't actually overwrite the file.

Yes there are ways to delete them. There are programs that are designed to delete files so they can't be recovered. Google "disk wiper" to find one that will take care of files that have been deleted. Basically, it will overwrite all parts of your drive listed as empty.

I agree with both posts.

1) Every image you view is likely stored on your hard drive.

2) The name "pandora" would give me pause (knowing what happened to the mythological Pandora when she ran software she didn't understand).

I'm not sure if this is the case for you but let me issue a general warning if you don't want anyone to know you've been viewing porn online:

Casual browsing of porn websites could well leave pictures scattered all around your hard drive that you don't know are there.

Casual browsing of porn websites will also leave a history of those visits on your hard drive as well. Deleting your history in your browser won't eliminate all evidence of your visits since Windows records it elsewhere as well.
