Computer users who managed to make it through Friday -- the strike date for the "Michelangelo" computer virus -- with their files intact shouldn't breathe too easy. Another virus is set to hit tomorrow, Friday the 13th.
Dubbed "Jerusalem" for the city in which it is thought to have originated, tomorrow's virus is decidedly less destructive than its March 6 kin, but a problem nonetheless. The Jerusalem virus, which has been around for about three years, shows up every Friday the 13th.
Like Michelangelo, the Jerusalem virus affects only International Business Machines Corp. equipment and clones.
Unlike Michelangelo, however, the Jerusalem virus obliterates files over a period of time, not immediately.
Left untreated, files hit by the Friday the 13th computer bug won't execute properly, requiring time-consuming reconstruction.
"It's not nearly as bad as Michelangelo, but it's still pretty nasty," said Wayne Carpenter, president of Jetics Inc. of Vienna, Va., an authorized agent for McAfee software, a popular anti-virus program.
