From F-Prot:
Name: No Frills
Size: 843
Type: Resident  COM/EXE-files
Origin: Australia
Repair: Yes
No Frills is a resident file infector which infects both COM and EXE files.
When an infected file is executed, the virus will install itself in memory 
nd
reserve 1kB for itself. At this time virus hooks INT 21h.
INT 21h handler defines the residence test and intercepts dos functions 4Bh
(load program), 3Dh (open file handle), 43h (get/set attribute) and 6Ch
(extended open/create). All EXE files that start with 'MZ' or 'ZM' and whose
names don't begin with "SC" are candidates for infection.
All COM files which do not have "CO" at the beginning of the filename are 
lso
candidates. Virus contains a copyright text inside its code which says '+-No
Frills 2.0 by Harry McBungus-+'. Virus size is 843 bytes.

So basically, it doesn't appear to do much other than spread.
