Invention

                       The invention that I dislike was Spam emails because these mails are sent to either infect your computer with a virus or acquire your confidential data, like usernames, passwords or credit card detail. Link contained in the mail would either lead you to download virus on your computer or redirect you to phishing site. The same spam email can be sent to millions of people at the same time and the addresses can often be guess.
                        Be careful who you give your email address to. Choose an email address which is difficult to guess. Don’t advertise your email address, for example by making it available on the internet. Check privacy policies and marketing carefully. If you buy something online check the company before giving your email address or personal information. Avoid responding to spam emails if you have any doubts about who has sent them.
