What is the resident scan?
The mission of the file resident is to monitor all the operations executed in
the computer in search of viruses. This means that each time an attempt is made
to run, copy, etc. a file, the resident will scan it to make sure that it is
free of viruses. Only if the file is clean will the operation in question be
completed; if it is contaminated, the operation will be cancelled.
Therefore, the file resident is responsible for giving a permanent protection
in everything associated with the handling of files. This includes any copying
of files to or from a networked computer, etc.
The file resident has a minimal impact on the performance of the system, and
offers the highest degrees of protection. Therefore, we always recommend that
our users have it enabled. Once it has been enabled and until it is disabled, the
file resident will start up each time the computer is booted.
