It demagnetizes the stripes on ALL of your credit cards. It reprograms your ATM access code, screws up the tracking on your VCR and uses subspace field harmonics to scratch any CD's you attempt to play. It will re-calibrate your refrigerator's coolness settings so all your ice cream melts and your milk curdles. It will program your phone autodial to call only your ex-spouses' number. This virus will mix antifreeze into your fish tank. It will drink all your beer. It will leave dirty socks on the coffee table when you are expecting company. Its radioactive emissions will cause your bellybutton fuzz (be honest, you have some) to migrate behind your ears. It will replace your shampoo with Nair and your Nair with Rogaine, all while dating your current boy/girlfriend behind your back and billing their hotel rendezvous to your Visa card. It will cause you to run with scissors and throw things in a way that is only fun until someone loses an eye. It will give you Dutch Elm Disease and Psitticosis. It will rewrite your backup files, changing all your active verbs to passive tense and incorporating undetectable misspellings which grossly change the interpretations of key sentences. It will leave the toilet seat up and leave your hair dryer plugged in dangerously close to a full bathtub. It will not only remove the forbidden tags from your mattresses and pillows, but it will also refill your skim milk with whole milk. It will replace all your luncheon meat with Spam. It will molecularly rearrange your cologne or perfume, causing it to smell like dill pickles. It is insidious and subtle. It is dangerous and terrifying to behold. It is also a rather interesting shade of mauve. These are just a few signs of infection.
You see, the Nimda worm really _will_ infect you if you so much as click on it. Not "open the attached file", just view it.
Which was the basic thing that Badtimes "couldn't" do.
