I read somewhere that, even if a personal file (such as a bank statement) is deleted from your hard drive, it is still really there. The computer just "forgets" where the file is. If someone wanted to search for it, they could still, in theory, find it. Someone sugested that you can use an eraser such as this: http://www.heidi.ie/eraser/ which permanently erases the data from your hard disc. I was wondering if this was necessary if I wanted to protect myself from hackers etc. I'm not even that sure how to use an eraser correctly.
I use removable storage to keep all my financial data, letters, photos and things. In theory, could someone get hold of these things if they had first been stored on my hard disc before being transferred on to removable storage.
I also have a good firewall and security system, but am perhaps a bit paranoid since my computer was hacked into last year!
Mod Edit: I fixed the link.
