1. A method of scanning for spyware on a computer, the method comprising:

  • setting a first scan rate for scanning for spyware;

    surveying processes executing on the computer at said first rate, thereby creating a first CPU usage value and a first disk usage value;

    repeating said surveying of processes, thereby creating a second CPU value and a second disk usage value, incrementing a counter each time said surveying is performed;

    calculating a difference between the first CPU and disk usage values and the second CPU and disk usage values;

    continuing said scanning of processes at the first scan rate if said difference is greater than a predetermined threshold; and

    if the predetermined threshold is not exceeded for a specific time period, increasing the first scan to a second scan rate.
