Typically, many sheets are printed out with only one line per page. These are being caused by worm called Adore which is coming in through the Internet. A worm is a program that spreads from computer to computer using known, easily exploitable bugs in computer operating systems. Once the worm gets in, it copies itself and attacks other computers in an effort to spread.
Worms are similar to viruses, in that they spread automatically from one computer to the next.
Adore is one of a new class of virus that attacks printers. They are largely automated attempts of the virus to spread, but the virus is not intelligent enough to tell the difference between a printer and a computer. There is no risk to the printer from the current attack, other than wasted paper. The Adore worm does not put pose any risk to campus data. No data is stored on the printers, and the worm cannot retrieve any data, but it has proven to be a nuisance.
