[comp.virus] WordPerfect and Jerusalem B virus

Michael_Kessler.Hum@mailgate.sfsu.edu (11/01/90)

We have been infected with a Jerusalem B virus, and apparently have
gotten rid of it.  However, 5 minutes later, we get a phone call from
a network user (always the same) having problems with Word Perfect
(lines doubling themselves and hiding the line under.  We checked
their hard disk, we checked the WP directory, I took down the network
and ran a check on all the partitions.  Nothing.  And then WordPerfect
starts acting up.  We can't figure out if now we are dealing with a
bug in WordPerfect or with a virus we can't detect.  Clearly WP.EXE
needs to be reinstalled once infected.  Is this true of *.FIL files?
Any suggestions?
