  • N.º del artículo: 10153
  • Actualizado: 03 ene 2013

This article describes intensive scanning options that can affect On-Demand scan performance.
NOTE: The below options are applicable to on-demand scans executed with sweep (SAV4) or savscan (SAV7/9)

What to do

Running a 'full' scan.

  • By default, Sophos Anti-Virus for UNIX/Linux performs a 'quick' scan which checks only the parts of files which are likely to contain a virus. If 'full' scanning is set, Sophos Anti-Virus for UNIX/Linux will be much slower.  Typically 'quick' scanning is five to ten times faster than 'full'.
  • Full scanning is enabled when the -full switch has been specified

Checking all files.

  • By default, Sophos Anti-Virus for UNIX/Linux will only check files defined as executables. If Sophos Anti-Virus for UNIX/Linux is checking all files, it will take longer than if only executable files are being checked.
  • To view a list of executable file extensions that are scanned, run this command:   
    • SAV4:  sweep -vv 
    • SAV7/9:  savscan -vv 
  • All files are scanned only when the -all switch has been specified

Other scanning options.

  • For more details on the available scanning options, run this command:
    • SAV4:  man sweep 
    • SAV7/9:  man savscan
