Changing the length of time that log files are maintained
Symantec Protection Engine creates a new log file for each day. You can specify the number of log files that Symantec Protection Engine retains to keep the log directory at a manageable size. Thus, when the maximum number of log files is reached, the oldest log file is removed on a daily basis. In its default configuration, this setting is enabled and the default value is 0. That means all the log files are retained.
