A virus comes and it looks like impossible to get rid of. Then.... maybe a month goes, and then someone sees how to delete it. Then he/she tells to others and they delete it too. Then....soon the virus is only history. If someone gets it, he just deletes it. Initcents time is now over. Some people have allready got rid of it before and now I can do it too and so. I dont think it takes much time before nearly everyone knows how to delete it. So dont be affraid you never get rid of it. Its not even hard.
