esetspac()
  ESETs scanner over it's preload library module.
  
  You need to set LD_PRELOAD to ESETs preload library (libesets_pac.so).
  You can do this by adding this line into /etc/sysconfig/sagator:
    LD_PRELOAD=/usr/lib/libesets_pac.so
  
  Usage: esets(prefix='/tmp/scand', logfile='/var/log/messages', reg=None)
  
  Where: prefix is a string, which defines directory and a part of filename
           to store scanned files, by default '/tmp/scand'.
         logfile is a string, which defines path to logfile. This parameter
           is used only when called from scanner daemon.
         reg is a regular expression, which defines log format. Default
           option is good for most of people. See source code for an example.
  
  Recommended settings for ESETS:
    # use /var/log/messages as logfile for scanner
    /etc/esets/esets.cfg
      [global]
      av_clean_mode = "none"
      action_av_infected = "reject"
      action_av_deleted = "reject"
      [pac]
      event_mask = "open:close"
      ctl_incl = "/tmp/scand:/var/spool/vscan/tmp/scand"
      action_av_deleted = "accept"
