THF does not normally help where illegal activators and other types of software cracks have been used.
If you'd paid for Avast or installed the free version you wouldn't be in the mess you are now in.

I suggest a Factory Restore but I hope you've got all your data backed up 'cos FR will overwrite it.

Let that be lesson - - don't use illegal software cracks.

At this point it sounds like you've FUBAR'd your system. A couple things to try...

1) Run Startup Repair. Sometimes you can run Startup Repair and it will repair the damaged components. There's no guarantee it'll work, but this route won't cause a loss in data, so I'd recommend running it first.

2) Reformat the machine. If Startup Repair can't repair the damaged components, only other option is to reformat. This will definitely fix it but you'll lose your data. So be careful before doing it, and backup whatever you can before you do it.

Once up and running, I can't stress how important it is that you start running backup. Doesn't matter if it's a disk imager (Macrium Reflect) or snapshot tool (RollBack Rx), but regardless, you could've easily recovered from this if you had a recovery tool in place.

I am not responsible for mishaps due to using this tool.
Please read about it carefully before using it.
Backup permissions and any information, before trying to reset them.
Be prepared that you may need to reinstall windows(C in order to fix your problem.

Yes thats exactly what i've used this software caused this problem and i cannot do anything now!!!

what did you download to activate avast?
sound like you need to backup your data and recover your windows 10
