Many thanks,

seems I am getting somewhere! After reading through some other threads, I reinstalled and now things are moving.

I have got task manager, regedit back…etc…etc and so far…things seem to be ticking.

I still have a problem with the PC not shutting down before, or restarting after the bootscan but at least avast is opening and running.

Am just doing a quick scan then will try another bootscan.

mbam log attached.

Many thanks
