Application 10/028,906
INTRODUCTION
The claims relate to techniques for controlling access to suspicious
files; i.e., access to potential malware such as viruses and worms.
(Specification 1:3-7.) Claim 1 is illustrative:
1. A computer program product for operating a computer to review
files for potential malware, comprising:
logging code operable to maintain a statistical log having an entry for
each file sent to the computer for review, each entry being arranged to store
a count value indicating the number of times that the file has been sent to the
computer for review and a value of one or more predetermined attributes
relating to the file;
weighting table code operable to maintain a weighting table
identifying, for each value of said one or more predetermined attributes, a
weighting indicating the likelihood that a file having that value of said one
or more predetermined attributes will be malware;
statistical log interface code operable, upon receipt of a file, to
determine with reference to the statistical log the count value relating to that
file;
action determination code operable, if the count value determined by
the statistical log interface code exceeds a predetermined threshold, to
reference the weighting table to determine the weighting to be associated
with the file, based on the value of said one or more predetermined attributes
associated with that file in the statistical log; and
action performing code operable to perform predetermined actions in
relation to the file dependent on the weighting determined by said action
determination code.
The Examiner relies on the following prior art references to show
