One of the most widespread viruses; alas, also oneof the most inspirational to new virus writers andwannabees. The Stoned family is vast.The virus apparently continues to remain common inmany parts of the world because it has become acceptedby many users as endemic but harmless (which, ofcourse, it isn't -- ask anyone who has suffered Stonedon a PC with a disc partition starting at 0.0.2!),with the regular result that little or no attempt ismade to remove or control it.Even with those variants of Stoned in which the message"Your PC is now Stoned!" is displayed, many usersfail to notice anything is amiss for weeks, months, oreven years. |
