Malwarebytes is no doubt one of the best anti-malware softwares available on the net – I have it as part of my default installation kit when I build/re-build a machine.

It will work on any machine with PowerShell v3 and greater. This one is easier to understand and doesn’t require wget.exe.

You can download the script here – it includes wget so all you have to do is double click the bat file ( MBDownloadLatestDefs.bat) I left in a REM (remark/comment) on the last line which will automatically copy the definitions file straight on to the root of a flash drive – all you need to do is remove the REM and replace driveLetter with the letter of your flash drive.

So with this information, we can script something up that will automatically put the latest database version integer in to the /data/rules.ref request. If it finds that /version.check returns a later version, it fires off a GET request to /data/rules.n.ref So it checks the local definitions database against /version.check.

You are a PC support specialist and like to carry around the latest definition files for portable anti-virus/malware applications on your USB.

You want to scan the machine with Malwarebytes but you do not have the latest definitions file… you obviously do not want to connect the machine to the internet in this state who knows what could be transmitted to/fro the machine.

You have an infected machine with all sorts of bad things like remote key-loggers etc.

Why would one want to manually download the definitions file I hear you ask. (Well, technically they do, however this comes as a 6.5MB file which needs to be installed before being able to download the file (disadvantage for those on-the-go)… also, the file is not updated very often – once a week it seems – See here) One of the annoying things about Malwarebytes though is the fact that they do not offer their definitions files to be downloaded manually.
