Definition Update for Microsoft Security Essentials


Recommended Posts

Hello everyone,
maybe someone has been through that and has knowledge to share
is there a .cab file for mseinstall.exe (microsoft security essentials)  so that I could add it to an offline  image using dism ?
I did some searching but found none, so I guess there's no .cab or msu for it ... ?
the other thing - I suppose I could add  the .exe to silent installers (with WinToolKit) but then I was wondering -  is it possible to add Definition Update for Microsoft Security Essentials KB2310138 (Definition 1.165.1048.0) ?

it is the package windows wants to download for ms security essentials after a fresh install and of course I wouldn't like to download it everytime I make a fresh install.

By "add" I mean add it to an offline image with dism, the same way I add e.g. IE11 or prerequsities for IE11. (the way I create my images is I first do things I can do using command line and for the rest I go for wintoolkit)

First thought is it does not make any sense to add updates (virus def) while there is no program installed yet that could use these definitions.

But let's say I did that, and then I go to Wintoolkit and add mse.exe (silent installer). Will it work ? I mean will the antivirus program use these definitions and updates itself without downloading them?

I'll try to do that myself but if anyone tried this before, I'll be glad to hear some feedback

There is no CAB but there is an EXE installer with the latest definitions. I think I have the FWLINK's listed in my repack for MSE

BTW if you want to integrate the updates you can also grab the installed definitions from %programdata%\microsoft\<mse_sub_dir>\{guid} in your current pc and add them to your mounted %programdata%\microsoft\<mse_sub_dir> \updates or \backup (one or the other of these will work)

Then when you install mse it will see the updates in programdata and add them automatically (I wanted to do the same with win8 but the folder permissions may not let you)

Thank you for your reply.
As I thought there's no .cab for MSE, I also find it hard to get the latest definitions .cab files. MS offers it as .exe for offline download and install but I can't find the .cab file which is downloaded by Windows Update (KB2310138 (Definition 1.165.1048.0).

Well, but that's ok since I am going to try your way.
When I try to access cataloges you mention Windows says you don't have permission, but eventually lets me in and lets me copy whatever I want.
Just to make sure if I got you right:
the folders are:
C:\ProgramData\Microsoft\Microsoft Antimalware\Definition Updates
and then:
C:\ProgramData\Microsoft\Microsoft Antimalware\Definition Updates\{1BCF080C-FF75-498B-A624-9FDE12884678}
C:\ProgramData\Microsoft\Microsoft Antimalware\Definition Updates\{AF144843-5794-4886-9922-84EAA5DD11D2}
These two contain files, especially the latter - there are other folders in the definition update directory (Backup, Updates, NISBackup) but they are empty.
Did you mean these two?

Copy the files in the guid folder (with the most) to the Backup folder in your mounted image (create dir if not exist)

When it comes time to install mse it will see these files and make a guid folder similar to where they came from originally and apply them automatically. You may still have to update but it will be a much smaller update that downloads the NIS updates (however you may also be able to copy these to the Backup folder and have them auto-applied)

      Here is something you guys might find useful, Its a must have if you are into driverpack making and it comes with InstallShield (used to extract drivers/files from installers with data1.cab/hdr packages created with InstallShield)
      Here is my SendTo style installer, I extracted the files from InstallShield 2018 SP1 (may also require Visual C++ Runtimes)

      i posted a little batch code a while back on this thread. it was meant to step by step do as the tutorial instructed, nothing more. but as time went by and i created more and more installers i frequently found myself in need of a little extra in terms of options and possibilities. so i threw together a little more complicated batch code to take advantage of some free software to help with the job.
      some of what it offers:
      - installation or portable setup
      - x64 & x86 builds
      - manages it's own path in system PATH
      - two convenient entires in the extended context menu
      - default settings in ini file
      - config.txt templates in sections of ini file
      - predefined environment variables for config.txt templates
      - customized sfx modules and possibility to add as many as you'd like
      - upx compression of sfx modules before executable creation
      - 3 ways of selecting a RunProgram / ExecuteFile / AutoInstall
      > by passing it as a parameter to batch
      > by using templates and calling them with switches
      > by a switch that tells the batch to look for a config.txt in the target folder
      - either way the text in query will always be auto encoded to utf-8
      - can run verbose, or silent / hidden
      - can create all exe binaries from all jobs to one selected folder
      - can create a .md5 file along with the binary
      - but most importantly, i.m.o; the !compile.cmd batch and configuring
      it to hold all your other commands, 3d-party tools, compilers etc
      to work in pre/post sequence of making the sfx binary. if you get used
      to it compiling your software and creating a simple installer is done in a jiffy
      suggestions, are most welcome! you can read the help file here
      all files + my compressed project can be found here

      After some time spent writing cab addon for larger number of files, i started to look for programs that automate most if not all tasks.
      I found out there are :
      Inf-Addon Maker - haven't found valid DL links (both here and at win-lite)
      DX Universal UpdatePack/Addon Creator (filename DXUPAC.exe DXTool_x64_005FE78D48FC1B11F7068FBBE6FC368A.exe) - DL links present but no options found to select Windows 7. Also at start program requires exe of hotfix/update (which i assumed this program creates as CAB output at end, not requires as input at start)
      Inf-Assistant - no valid DL links
      Are there any usable Win7 INF addon cab makers then ?
      EDIT: I downloaded DXUPAC.exe and it was staring in my face the whole time  :doh:  It is split into several "send to" targets so i did not it see as one single package to work with. Which reminds me : do these pieces of DXUPAC have source code somewhere ?
      I kind of like using Notepad2 and manually assembling the INF files.

      I would like to add nircmd via true addon CAB (a great little utility by Nir Sofer) to my Win7 x64 offline image (ie for making ISO out of it later).
      It has both x86 and x64 versions.
      SInce i intend to use it on x64 Windows, it means that calling application (usually cmd.exe) will call the corresponding version of nircmd (x86 cmd calls x86 nircmd and respectively x64 cmd.exe calls x64 version of nircmd).
      Now a problem : i can make a CAB file that holds both versions under different names in same folder inside CAB, but since in future i intend to add other dual-bitness applications, this will be a problem for me.
      I have my CAB referenced in Entries.ini like so
      [txtsetup_files]AddUtils.cab = 1,,,,,,_x,,3,3Note that i have left out other relevant information to make this post short and to the point.
      I would like to package both versions of nircmd in CAB file under different subdirectories, like so :
      MYCABFILE.CAB   < CAB file itself\X86VER\nircmd.exe  < first version in subdirectory\X64VER\nircmd.exe < second version in other subdirectoryI was reading INF reference documentation on MS site and it mentions multiple directories, but it is unclear to me if the above is possible.   There are two descriptions that don't explain this well enough :
      [SourceDisksNames]diskid = disk-description[,[tag-or-cab-file],[unused],[path],[flags][,tag-file]]I don't know if "path" part refers to my above case of subdirectories in CAB file or some other location.
      Second one is
      [SourceDisksFiles]filename=diskid[,[ subdir][,size]]Also, i'm not sure to what "subdir" points to.
      I was trying to find other true addons as examples (so far, they have been useful), and closest one is for Notepad2, similar to what i need, but it either copies x86 or x64 version (as defined in section names), and i need BOTH versions of nircmd.exe to be copied in their respective directories (%SystemRoot%\System32 and %SystemRoot%\SysWOW64).
      I hope i haven't overcomplicated my post, i just wanted to be as specific as possible.

      I have uploaded the offline version of the repository by abbodi1406.
      Downloaded with WHDownloader v0.0.1.9, identical pack from 30# July 2015.

      They are prepared, means converted to .cab for faster integrate.
