Avast Premier, lost password, can't uninstall?

Could someone please help me
I’ve forgotten the password for my Avast Premier and was trying to uninstall it so I could reinstall and start again, but it keeps asking me for the password and won’t let me uninstall, so could someone please tell me how to uninstall.
The reason I want to start again is because the VPN is asking me to buy it although up until now I thought it was part of Premier, so you see my problem.
Thank you

Thank you all so much I’ve managed to uninstall and reinstall and I’ll look into the other VPN, but I did like the Avast version so I’ll think about it.
But as I said thank you all. ;D

Does Avast VPN come with Avast Premier?
I ask because every time I try to Go Private it tells me I can’t and must buy it, but up until now I’ve been using it with Premier without having to buy it specifically so I don’t know what’s going on and in Components it says that VPN is installed.
Anyone have any ideas?

No it’s a separate purchase. There is a limited trial.
