I noticed the cleaning mode listed in the command line scanner is as follows: Code: ECLS Command-line scanner, version 4.0.424.0, (C) 1992-2009 ESET, spol. s r.o. ... /clean-mode=MODE use cleaning MODE for infected objects. Available options: none, standard (default), strict, rigorous, delete ... None, standard, and strict are in the GUI and explained. Delete seem self-explanatory. What is the rigorous option? How does it compare to the other options.
