Abstract:
Although everything in computing industry moves faster, the
processor, memory speed, memory size, storage space etc. there is no
improvement in virus scanning time. Although the processing speed has
substantially increased, a typical full scanning is still taking several hours
for an average computer. There is a serious need to improve the scanning time.
Contradiction is a stage of problem solving where the nature
of the actual problem is clearly explained in terms of at least two parameters,
one improving and another worsening. While emphasizing one parameter
strengthens the system position emphasizing another parameter weakens the
system.
In conventional methods a problem solver has to make a
perfect balance between these conflicting parameters, where the situation is
neither too much on one side nor too much on the other. The results of those
methods, although increase the speed of virus scanning, results in
disadvantages like load on processor, increase in false positives and
compromise on security. The objective of TRIZ is not to accept a tradeoff
between the speed of scanning and those other difficulties but to resolve the
contradictions so that the speed of scanning increases without compromising
with security and other harmful results.
