Yes. Companies like Microsoft, HP, and Norton leave holes in the computer software they produce allowing hackers to break into them over the Internet. +++ The Internet is about the only way it can be hacked, unless the hacker has personal, physical access to a terminal on the specific system such as a company's internal network. Most hacking is covert, some is overt by fraud. A typical ploy for the latter is to telephone unsuspecting private computer owners and say "I'm from the 'Windows Corporation' and your computer has reported a fault". Fall for it, and you end up giving the hackers remote control of your computer via the Internet.
