Can't log in, can't reset password, can't delete Avast.

Hi,
I can’t do anything with Avast, it won’t let me log in with my password (says it’s the wrong password, although I hadn’t changed it).
On the login page, there is no password reset.
I can’t get rid of this app, and it continues to block other apps I need, and continues to intrude with irritating pop ups I don’t need while I’m in the middle of something.
Other than wiping my entire drive to get rid of this app, what can I do?
Cheers.

NOTE: What caused me to write this, is that it blocked my new VPN software, and I can’t get it out of the vault. Any ideas about how I can reinstate it, if I can’t get into Avast?

I can log in here, but the actual app just keeps me locked out, and I can’t do anything with it.

Oh, and the Captcha on this page is bloody irritating too.

Thanks Pondus.
Yeah, I ended up finding that, and managed to delete Avast.
Problem solved.
