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 "
