i don't know of any viruses, but you can set a comp on fire with a 3-1/2 diskette! take it apart slowly, to ensure you can put it back together, and there will be the outer case, 2pieces of coth, and the other outer case. , in between the piece of cloth, will be this black pice of plastic that holds the information. if your grind up a bunch of blue headed matches into a powder, put it on evenly, cover with clear nail polish, put it all back together after letting dry over night, and seal up the edges with more nail polish so it wont fall apart, when you put it into a comp, the lazer will try to read the info off the black plastic, heatup the match dust and set it on fire. it'll soon melt the inner plastic of the somp and then set that on fire. >:D
