Interesting post that explain simply and visually to the sort of computer user who can’t begin
to fathom why miscreants would want to hack into his PC. “I don’t bank
online, I don’t store sensitive information on my machine! I only use it
to check email. What could hackers possibly want with this hunk of
junk?,” are all common refrains from this type of user.
