Flash, also known as, Adobe Flash Player and Macromedia Flash Player, is a major computer virus affecting multiple operating systems for over 10 years. The virus disguises itself as a game loader (for cheap little website games like the ones found on Facebook) as well as some video sites, but in reality it opens your machine up to hundreds of security risks, and loads up millions of not only annoying but extremely CPU intensive advertisements on websites that often make your web browser either start to lag like crazy or just simply crash unless you have a very powerful computer. My 2GHz C2D system could barely handle Flash ads, the CPU fan had to come on full speed to cool it as it ran so hot, just from ADS! Almost all computer security experts agree that Flash should NEVER be installed just for the security risks alone, never mind all the other stuff this virus leads to. Apple is one of the first companies to no longer preinstall Flash on their computers, and it is not usable period on their mobile devices. It is recommended that if you have A PC or an older Mac which ships with Flash, you remove it immediately.
Person 1: Did you know that Flash has had over 100 unaddressed major security holes for over a year now, leading to many extremely harmful viruses affecting PC's and Android phones, and even Mac's?
Person 2: I don't care, I wanna watch my porno videos and play these poorly done games on Facebook!
