Grimefighter Will NOT connect to my internet

I know I got my password for my WIFI correct, my dad is the one who made it and I have used it plenty of times for my tablet or to connect to the WIFI with my computer but Grimefighter WILL NOT connect…and I wasted MONEY ON THIS!!! Please help me because it supposedly can “fix” my computer because I have tried everything I have on my computer and nothing is fixing my problem! Either help me get this fixed or please give me a refund cause I have not gotten to actually USE Grimefighter so I wasted my money…and I am very upset and will most likely not recommend avast in the future if this isn’t resolved. Thank you…
