Mr. Know-It-All has the answers to even the really tough questions.
Question:OK, now that I have Symantec NAVOS2 running the way I want (see Mr. Know-It-All from last month), is there a way to update the virus signatures other than with LiveUpdate? Answer:Yes, the Symantec AntiVirus signatures for all the supported platforms are available at Symantec Virus Updates The OS/2 signatures are named:
mmddo32.zip
where mm and dd are the month and day the signatures were released.
To update your signatures, unzip the zip file to the Incoming subdirectory of your NAVOS2 installation. The next time NAVOS2 starts, it will detect the new signatures and prepare them for use. This is will slow down NAVOS2 startup and the main dialog will be slow to draw, so be patient. To save you some time, one of Mr. Know-It-All's friends has built a REXX script to automate the download and unzip. You will need working copies of WGet and unzip to use the WGetNavOS2Update script which you can download now. Before you can use this script, you need to change some global variables to match your installation.
To display the command line options, run the script as:
WGetNavOS2Update ?
Normally, you will run the script with no options.
By default, the script starts at today's date and works back for up to 6 days looking for a set of signatures to download. It stops after a set is successfully downloaded or if it finds a previously downloaded set in the download directory or if it runs out of days. The start date can be overridden from the command line. If a new set of signatures is downloaded, they are unzipped to the Incoming directory. When the script exits, it shuts down the current session. This is because the script is designed to be run unattended. This exit can be somewhat unexpected if the script is run from the command line. If you want to suppress this behavior, delete the '@exit' statement near line 96. If you use Relish or some other scheduler, you can schedule the script to run at a regular interval. Then when you run a virus scan you will be sure to have fresh signatures. Symantec seems to update the signature files once a week unless there is an outbreak of some sort.
OS/2 is his specialty and sharing solutions is his passion Mr. Know-It-All lives in Southern California.
