Can you at least tell me what if the 'page faults' into the Windows Task Manager (a column that could be shown there)?
ashserv.exe has a 'million' of page faults... more than any other application and/or service... Is this an error? Is it the cause of system failure or freeze?
Well in a sense, it's not ideal but it's really not a problem either.
Page faults are caused by almost anything a program does - a 'page fault' is a process in which a piece of memory is being recalled from the paging file. Since ashServ.exe is polling the system (checking the status) in pretty short intervals (couple of seconds), if you have long uptimes, you'll see a huge number of page faults. They accumulate...
Actually the current version of avast (4.1) is much better in this aspect than the original 4.0. In other words, we're trying to push this value to minimum...
Hope this helps,
