Malwarbytes Database Update very slow


Recommended Posts

Over the past two weeks, Malwarebytes has been incredibly slow in downloading its database updates. Even when I try to download the offline installer from the Malwarebytes website it takes over 30 mins for it to download (appx 100 kbs). This is despite doing a speed test which gives me 50 mps.

I am using Malwarebytes Version: 4.5.25.256, with update package version 1.067248 and component package version 1.0.1957.

Hi Porthos, I have tracked it to some sort of network issue, but it seems to have something to do with my ISP. Either they or Malwarebytes is throttling the connection. When I switch from my ISP to hotspot on my phone using a different network provider, malwarebytes downloads it updates as quickly as usual. I have measured this using the download of the malwarebytes offline installer from the malwarebytes website as a proxy indicator.

Using my ISP, download speeds are around approx 150 kbs. When using my phone hotspot and a different provider, it goes up to approx 10 mbs. (see screenshots attached).

I have tested this phenomenon on a laptop and a desktop with the same results. I have also re-created this throttling issue on another household's connection with the same ISP. Our accounts are not linked.

I've contacted the ISP and explained all this and they advised me to check with malwarebytes. Could it be something that is on malwarebytes end that is throttling connection to my ISP? I am based in Australia and my ISP is one of the top 2 providerds - Telstra.

If the downloads of library packages are taking this long, it is severely limiting the usability of malwarebytes as it has been taking up to 30 mins for the desktop client to download library updates before it finishing a scan.

I see you are using the free version. If it was the paid version it would auto-update the definitions every hour by default. When you scan with the free version the databases are alot larger and take a bit of time to update.

Have you tried to update the database manually before doing the scan? Try it.

I do not think the offline installer is on the same server as the database updates.

Yes, I have tried using the manual update and it goes through very slowly. When I try on a computer that is connected to a different ISP, it downloads quickly as it should. But for some reason, when it's using my ISP it is very slow. I only used the offline installer download as a bit of a proxy as I couldn't measure the speeds at which the desktop client downloads.

As a mitigation step, I have taken to manually updating always prior to if I needed it to scan something. If I don't do this and try to scan something, the scan has been stuck at 'checking for updates' at around 30 mins before it fully downloads. Normally this process takes no more than 20 seconds.

This is the issue. I would reboot your modem and see if it helps any.

Yes, I have rebooted the modem, but the issue still persists. This advice was suggested by the ISP.

As an experiment, I asked a friend of mine who lives in another house but who uses the same ISP to see if he could repeat the slow download issue with malwarebytes and it affected him as well.

But the normal download speed resumed when he tried it through his work VPN for example.

I believe this indicates that it could be an issue with servers on either my ISP or malwarebytes end? The bandwidth appears to be throttled or slowed down in some way.

Please try using an alternate DNS server such as Google DNS as instructed in this article or OpenDNS as detailed in this article.

Please consider changing your default DNS Server settings. Please choose one provider only

DNS is what lets users connect to websites using domain names instead of IP addresses
