[ILUG] Linux Virus reported by file/magic!

[John A. Kinsella]

Hi.
A student brought me a short text file on a floppy (dos format).

Mounted floppy, & printed file
get blank sheet!

When I ran /usr/bin/file on txt file, get

file /tmp/a.mm
/tmp/a.mm: fsav (linux) virus (29545-120)

Had a look at /usr/share/magic & find
grep -i virus  /usr/share/magic
# fsav:  file(1) magic for datafellows fsav virus definition files
0	beshort		0x1575		fsav (linux) macro virus
>11	leshort		>0		fsav (linux) virus (%d-

What gives?

I take it that some garbage in file is confusing "file"?

Any thots?

John

PS

I am embedding file here as ilug doesnt allow attachments in postings.

mu = 1;
xlist = [];
x0 = [2,2];
xlist = x0;
k=1;
lambda = 1;
kmax = 100;
options = optimset('Largescale','off');
while k<kmax %&(gradient =0)
    con = (x.^2 + y.^2 - 1);
    %con = (x(1)^2 + x(2)^2 - 1);

    abs(con)>=sqrt(eps);
    [x,fval,lambda,exitflag,output]=fmincon('objworking',x0,options,[],[],[],[],[],[],'confun33');
    mu = mu*2;
    lambdanew = lambda +2*mu*con;
    xlist=[xlist' x']';
    k=k+1;
end
