Thank you for answer. I think only clean install. If you update trought gui, all settings stay unchanged. If i looked to performance monitor, avast service reading pagefile so i looked to exceptions and there is nothing. I don't know if previous version doing this but all exceptions should be visible. But maybe is only hidden, because if i save eicar test code to .txt or .ini nothing happpend but if i save it as .inf, is immediately detected.
