Do you mean ashserve.exe is always using 90% cpu usage? This should not happen.
Ashserve.exe does use various levels of cpu when avast is scanning files (I think ashserve.exe is the resident shield), but on my system it always sits at 0% when the system isn’t loading files.
Hope this helps.
Thanks for reply,
No, ashserve.exe is not using 90% all the time only occasionally.
Whilst i am reading your posting its hovering around 1.25%.
I seem to have two Avast exe running Ashserve & Ashmaisv, which is hovering around 0.50%.
