Iran's nuclear agency is trying to combat a complex computer worm that has affected industrial sites throughout the country and is capable of taking over power plants, Iranian media reports said.
I've included every type of computer virus in this article that I felt was relevant, but this isn't a list of every type of virus known to man. Also, I did not include any worms or trojans, two common threats that are similar to viruses but technically not the same. If there is a specific type of virus that you feel was missed and is important, let us know in the comments.
