VirtualBox very slow with MBAM real-time protection enabled

[mbite]

Windows 8.1 Pro x64

VirtualBox 4.3.14

Linux guests running inside VB (e.g. Linux Mint 17 MATE x64)

MBAM Premium 2.0.2.1012

 

With MBAM enabled, VirtualBox guests are painfully slow to use. There's mouse lag, keyboard lag, etc. MBAM service also seems to constantly take up 2-3% CPU.

 

If I quit MBAM, then VirtualBox returns to normal, the guest Linux OS running inside is responsive.

 

The following MBAM settings make a noticeable difference:

- Advanced Settings > Enable self protection module

- Detection and Protection > Malware Protection Enabled

 

I could turn "Enable self protection module" off and I will notice a difference, but still not normal behavior with real-time malware protection enabled.

 

I tried resetting MBAM to recommended settings, VB is still not usable.

 

Please investigate and release a fix for MBAM as in its current form it is not usable if I can't make use of VirtualBox.

I should clarify that Windows 8.1 Pro x64 is the host OS where MBAM and VirtualBox are running side by side. Inside VirtualBox I only run Linux guests, there's no MBAM running inside VB of course.

Anyone else seeing the same issue?

Anyone from MBAM Support care to comment please?

There is nothing I can think of that would cause an issue like this and I don't recall seeing any posts for this same issue either.

 

Please read the following and post back the 3 requested logs.

The issue is real, have you tried it? Somehow MBAM monitors the mouse or similar and VirtualBox is very very sluggish when MBAM is running. If I shut down MBAM, VirtualBox is back to normal, so there's clearly some incompatibility between the two. I had problems not too long ago with MBAM and OpenVPN, I reported the problem and it got fixed though it took a while. Unfortunately my experience with MBAM v2 has not been very good, compared to the 1.x version.

 

As for providing logs, I value my privacy and I will not provide any logs in public forums. Please contact me for alternate ways I can provide the info you need in a private way.

Adding an exclusion for C:\Program Files\Oracle\VirtualBox seems to help, it makes it a lot better, but it still doesn't seem to behave as well as when MBAM is not running at all.
