[comp.virus] Help! Anybody here of this virus?

gregs@cs.washington.edu (12/05/90)

We've discovered what looks like a virus on our DOS PC's, and would like
any feedback from anybody familiar with the following symptoms:

1. io.sys size increased by 66 bytes;
2. io errors create four files that loop endlessly,
   i.e. a.bat to b.bat to c.bat to d.bat to a.bat;
3. non-movable blocks inserted on the hard drive: is this a worm?

Please respond by email.

Thanks,
Greg Sharp
