I have both of them in my avast folder, I can recall doing a patch some time ago, but I don’t know if it was for this particular fix/patch.

Well the - aswVmm.dll and aswVmm.dll.sum files in conjunction are generally used for a patch update, the .sum file aswVmm.dll.sum is used to prevent avast’s integrity check replacing the patched/fixed version of aswVmm.dll with an old version.

Are yours the same date/time and file size as the ones in my avast folder ?
