Spyware is designed to snoop upon our computers and steal files and data. One common weapon in spywares arsenal is the ability to seize passwords by intercepting keypresses (known as keylogging) as users log into their email or access their online bank accounts. Some banks have responded to this by producing virtual keyboards on their login pages which dont require you to type a password but instead choose the correct sequence of letters and numbers with your mouse instead.”]
