Issue With Malicious Website Blocking in v1.65.0.1400

Recommended Posts

First off, I'd like to say I've used MBAM for years and by far it's my favorite anti-malware software. It has an all around superior detection rate, it runs smoothly, and boosts my confidence while browsing or downloading new files. I recently upgraded to pro this year (long overdue) and I feel confident seeing that little "M" icon in my tray.

With that being said, after updating to the latest version I began experiencing issues with Spotify playback while the malicious website blocking module is enabled. Using DPC Latency Checker (see below), I've traced the issue to MBAM.

"Thesycon’s DPC Latency Checker is a Windows tool that analyses the capabilities of a computer system to handle real-time data streams properly. It may help to find the cause for interruptions in real-time audio and video streams, also known as drop-outs. The program supports Windows 7, Windows 7 x64, Windows Vista, Windows Vista x64, Windows Server 2003, Windows Server 2003 x64, Windows XP, Windows XP x64, Windows 2000."

It is available here: http://www.thesycon....ncy_check.shtml

This screenshot shows my latency while the protection module is enabled. Keep in mind Spotify is not open and Windows Defender is disabled.


The period where website blocking is enabled causes terrible latency which is reflected with choppy audio/video playback. When the module is disabled, the latency drops and audio/video playback is normal.

This occurs regardless of whether a browser is open or not. I use Chrome/IE9/Firefox for web development testing purposes.

Please let me know if this is a common issue and whether there's a fix or workaround available (besides disabling the website blocking module).

Thanks for the help.

Well I stream HD content movies with no stutter or lag from various sites so I'd have to guess there is probably something going on with your system.

Yes there is certainly extra resources used with the protection module enabled but none of my systems suffer from it being on.

Please run the following mbam-check tool so that we can get a better look at what's going on.

Create an mbam-check log:

Download mbam-check.exe from here and save it to your desktop


Double-click on mbam-check.exe to run it. When done it should then open a log file

Please attach the log to your next reply, it should be on your desktop as "CheckResults.txt"

Next, please download DDS from one of the locations below and save it to your desktop.

here: http://download.bleepingcomputer.com/sUBs/dds.scr


here: http://download.bleepingcomputer.com/sUBs/dds.com

Temporarily disable any script blocker if your Anti-Virus/Anti-Malware has it.

Once downloaded you can disconnect from the Internet and disable your Ant-Virus temporarily if needed.

Then double click dds.scr or dds.com to run the tool, on Vista or Win 7 right click and select Run as administrator

Click the Run button if prompted with an Open File - Security Warning dialog box.

A black DOS console should open and run for a moment.

When done, DDS will open two (2) logs:



Save both reports to your desktop

Please attach the following logs in your next reply: DDS.txt and Attach.txt

You can ignore the note about zipping the Attach.txt file and just attach it to your reply.

Thank you
