摘要: A computer virus scanning system is described in which during the scanning operation a measurement value indicative of the amount of data processing performed is calculated and this measurement value used to trigger breaks in the virus scanning operation. The triggered breaks can be used to perform a determination as to whether or not the virus scanning operations should be early terminated. One possibility is to measure the total size of the data processed during the virus scanning operation and calculate a ratio of this compared to the size of the computer file being virus scanned. If this calculated ratio exceeds a predetermined threshold, then virus scanning may be terminated. Another possibility is to associate a complexity value with each of a plurality of tests applied in the virus scanning operation. A total for these complexity values may be used to trigger the breaks and also to trigger early termination upon exceeding of respective threshold levels.
