    c) whenever an attempt to write data to said device drivers is intercepted performing the following steps;

    c.3) calculating CRC code of the data to be written to said device;

    c.4) if the calculated CRC code equals to one of the CRC codes that were previously stored in the memory of said computerized system terminating said write data attempt; and
