My system M2N4 SLI ASUS motherboard AMD X64 5400 4 gig DDR2 ram Nividia Geoforce 9800 Sound Blaster Recon 3D PCie Windows 8 pro All drivers and Bios up to date. I am running Windows 8 32 bit, I did an update instead of a clean install so I could not go to a 64bit system, In my case it isn't locking but very high latency. Have used Malwarebytes for quite some time in XP-SP3 without any issues. I installed Windows 8 back in November when it first became available. My computer is at the heart of my AV system I had no issues at all until about the later part of February when I started to experience dropouts and stuttering in audio playback. I loaded a utility called DPC Latency Checker and with its graph running in real time I pulled up the task manager and started to turn on and off running processes. When finally shut down MWBS the latency dropped to a normal range and the dropouts and stuttering stopped immediately. A looked at the CPU and RAM usage graphs show the system is far from being tapped out resource wise. I have not tried shutting down the site filter this is something I really don't need as I have a firefox addon that does that quite well. I like how Malwarebytes works, I really do not want to go elsewhere. Incidentally I work at the VA and I finally got my turkey XP-Pro machine changed out for Windows 7 last week. At home I was starting to wonder if I made a mistake going to W8, and not W7 it turns out the stuff that irritates me on W8 is also found on W7, and I don't have a problem with the Metro stuff.
