Password online vs on my PC

I have reset my Avast PW several times, and nothing I change it to will reflect the same on my PC interface. I am trying to disable the virus protection for 1 hour, and that is a viable option, but the pop up for the PW shows and when I have tried ever single known PW or phrase I use, it tells me that is the wrong PW! I am beyond livid at this point and would greatly appreciate some input!

Which Avast…? (Free/Pro/IS/Premier)

Having the same issue. Still trying to sort it out 3 hours later. Any answers would be soooo very welcome and might prevent this poor defenseless laptop from a severe beating >:(

Try a clean install.
