Well, VIRSTOP (or Quick scan) will not detect as many viruses as
F-PROT Secure scan.  It will miss all MtE viruses for example, and
most of the viruses which cannot be found using a signature-based
approach. While Secure scan will detect around 99% of all viruses,
Quick scan may detect only around 90% (however, it will detect a much
higher percentage of "in-the-wild" viruses).

Well, 12K isn't exactly small....and of that only 2K is code, the rest
is the signatures.  Of course, by using the /DISK command-line switch
you can get VIRSTOP's memory usage down to 2K, as the cost of a small
delay when running any program.
