Avast 17.4.2294 build 17.4.3482.0 causing midi and audio timing problems.

Audio Interface: Focusrite 2i2 - 2.5.1 driver
Midi Interface: Behringer UMX610 keyboard

Using Avast free. Recently Avast fixed an issue (after an Avast update) that stopped Reaper DAW from starting the playhead

This is happening on everything I record. Everything needs to be shifted 1/32nd to the right as everything except for the first note (midi) or sample (audio) is being recorded 1/32nd too early. It’s also happening with another DAW I installed to test. It’s obviously a PC issue, but it’s driving me nuts.

I have a feeling it’s got something to do with my AV (Avast) but I’ve disabled and even uninstalled Avast, and the problem still persists. The reason I think it has something to do with my AV, is that as soon as I updated it to the latest version on my laptop, then I got the same issue as I now have on my PC.

I think Avast has made a change that persist even after Avast is uninstalled. It could be something else entirely, but I’m just trying to figure this out. If you can’t help that’s OK, I was hoping that other users may be experiencing the same issue, particularly those using Avast AV.

I’ve uninstalled my audio and midi drivers, cleaned out any USB entries using USB-Deview, and re-installed but the same issue…

At the time that this issue started happening there was a known Avast bug that stopped the playhead from starting. See: http://forum.cockos.com/showpost.php?p=1841087&postcount=21

Well, if you uninstalled Avast, I doubt it’s related.

As I said my laptop was fine until Avast updated itself…

When you removed Avast, did you use the avast removal tool ???

Well not in this one. The problem with posting in separate posts is getting only partial help.
