Help for Check system window
----------------------------
The Check system pop-up window allows you to check your system's drives
(both local and LAN attached) for viruses and to change the way this
check is done. If a virus is found during this check, you will be given
the option to remove it.
Select the drives to check, the files to check, and in which files to
look for known viruses. Then select Execute to perform the check.
If the Advanced options selected check box is checked, the Drives to
check and Files to check information is taken from the Advanced options
settings.
Help for Drives to check
________________________
You can select the drives to be checked for viruses. If you select Fixed
drives, all of the local fixed drives on your system will be checked. If
you select Network drives, all network-based server drives to which you
are linked will be checked. All directories on the specified drives are
checked. When you want to check some other combination of drives or
directories, you must specify them by selecting the Advanced options push
button. You must specify at least one drive to check, either by selecting
Fixed drives, Network drives, or by selecting drives using Advanced
options.
Usually, you want to check all local fixed drives to determine if there
is a virus on your own system. You do not usually want to check all
network drives. Because network drives tend to have a large number of
files, checking them can take a substantial amount of time. If several
systems on the network are checking all network drives, it will reduce
the performance of these drives for other network users. When network
drives are checked, they should usually be checked by only one system and
only when the network usage is low.
Help for Files to check on system
_________________________________
You can select whether program files or all files are to be checked.
Selecting Program files tells IBM AntiVirus/DOS to check files that are
normally executable on the specified drives. These are files that have
file types of BAT, BIN, CMD, COM, DOS, DLL, EXE, OS2, OV?, PRG and SYS.
Selecting All files tells IBM AntiVirus/DOS to check all files on the
specified drives. In either case, the master boot record and all active
partition boot records on any specified local, fixed drive are also
checked, including Boot Manager boot records. When a file cannot be
accessed for some reason, it is skipped and checking continues.
Normally, viruses only infect program files. Checking program files is
the correct thing to do in most cases. The only exceptions are if an
executable file has been renamed to some other file type or if a program
uses overlay files that have some other file type. Usually, files other
than program files are data files that do not become infected with
viruses. Checking all files finds viruses, no matter what files they are
in, but it takes longer because more files need to be checked.
Help for Look for known viruses in
__________________________________
IBM AntiVirus/DOS checks several features of boot records and files to
determine if they are infected. One of these checks is to scan the boot
record or file for known viruses. You can select whether IBM
AntiVirus/DOS scans all specified files and boots records for viruses or
only scans those that have changed or are new since the last check. Boot
records and files that you have specified are always checked for other
features, even if you choose not to scan those that have not changed.
If you select Only new/changed files, files and boot records are checked
to see if they are new or changed and are only scanned for known viruses
if they are. Viruses must change the boot records and files they infect
in order to infect them. Because there were no viruses the last time a
check was performed, the only boot records or files that can be infected
now are those that have changed. Checking only those that have changed is
usually the correct thing to do.
If you select Even unchanged files, all specified files and boot records
are scanned, whether they have changed or not. This takes substantially
longer than selecting Only new/changed files.
Help for Advanced options choice
________________________________
Use Advanced options to select more complex combinations of drives or
files to check. If the Selected check box is checked, advanced options
are in effect. In this case, the drives and files to check are specified
on the Advanced options pop-up window, rather than on the Check system
pop-up window.
To choose advanced options, select the Advanced options push button. To
deselect advanced options, uncheck the Selected check box in the Check
system pop-up window.
Help for Check system Default settings
______________________________________
Selecting the Default settings push button returns the settings on the
Check system pop-up window to their default and recommended values. Any
other values that had been specified are discarded.
The Save settings push button needs to be selected to save the default
settings for subsequent IBM AntiVirus/DOS sessions.
Help for Check system Save settings
___________________________________
Selecting the Save settings push button saves the settings on the Check
system pop-up window. When you select the Check system menu item at a
later time, these saved settings are used.
Help for Check system Execute
_____________________________
Select the Execute push button to check the specified drives for viruses
now. The files that are checked are the ones that you have specified in
the Files to check box. If a virus is found on any of the selected disks,
you will be given the option to remove the virus and to do a more
thorough search to make sure all instances of the virus are eliminated.
Help for Check system Cancel
____________________________
Use Cancel to close the Check system pop-up window and to return to the
previous window. When you select the Cancel push button, any settings on
this pop-up window that you have not saved are discarded.
