Audio latency

[ssoundman]

I had the exact same audio symptoms as matpan. I'm running the latest version of MBAM (1.75.0.1300) on Win7 64bit on a 256GB SSD inside an HP 8760w Elitebook with 8GB RAM.

I can confirm that the "site blocking" feature of MBAM causes excessive latencies of Deferred Procedure Calls (DPCs) and I confirmed this using the DPC Latency Checker tool available at http://www.thesycon....ncy_check.shtml.

I tried to add a screenshot to this post bould could not. But my screenshot clearly shows the effect on latency when I toggled the "site blocking" on and off. If you can provide me with a way to post the jpg file I'll be happy to make it available.

It made no difference whether I had other protective software running or not. After a fresh boot-up I ran the latency checker tool and toggled MBAM's "site blocking" and saw the results I describe. With that feature turned off latency plummeted to "normal", acceptable levels.

If I can help by providing further details or the screenshots I'll be happy to.

Meanwhile, MBAM remains my go-to and most relied-on malware protection. I'll simply leave "site blocking" disabled for now, thank you anyway.

Good luck - Dave

I forgot to mention that I performed quite a lot of hardware and driver investigation before discovering that the issue seemed to be cause by the "site blocking" feature.

Hmm... does this latency issue need to go to another topic or is it ok here?

[AdvancedSetup]

Yes we are looking into this issue and and soon as we find a solution for it we will post about it and hopefully push out an automatic update to correct it.

For now if your computer is impacted by it you can disable the Web blocker and the file blocker will still function to protect the box until a resolution is found.

Thank you

Thank you, Advanced Setup. I have done this and am still relying on MBAM's excellent protection (and support).

It seems that my posts have been separated from matpan's, who I referenced in my first post. His was moved to the topic: "Audio Lag MBAM" while mine was moved to this "Audio Latency" topic.

Hmm... I'm not sure why our comments would have been separated from each other, but to catch up anyone following all this, here's matpan's original problem description, which I also was seeing:

"There is a problem with new version of MBAM 1.75.0.1300. When i use protections and "Site blocking" option is in use, i'm getting very high latensy on

Windows 7 home premium 64-bit. Especially when i hear mp3 music through winamp "Site blocking" causes my mouse and audio to stutter. It is really annoying and makes

me not want to hear music

"

They were split so that each can be tracked on it's own. Having multiple users post on the same topic makes it almost impossible to manage and help the user because a fix for your computer or his may or may not be the same.

Ah, I see. Thanks, Ron!

Please uninstall your current version of Malwarebytes and reboot. Then install the latest version of MBAM and check for updates and allow it to update itself.

The try running a Quick Scan and then post back that new log and let me know how it's working now.

Thanks

[ssoundman]

Much better latency following the uninstall, reboot, reinstall, update and quick scan. But still higher with website blocking turned on than with it off. I wish I could provide you with screenshots of the results of the latency scan.

Yes that should have reduced it quite a bit but not completely gone especially for older systems on XP.

They are working on a new method that hopefully will be available in a future update that should resolve this for everyone.

Thanks ssoundman
