Supera is finding malwares in my Cookies, and Avast not

Hello Guys, and good morning from Brazil. 8)
I’m having problems with my system (W8), it’s being very slow for some tasks, principally when I need to work with my Office 2007.
I’m trying to find the non conformity, but it’s not being easy.
Then I installed SUPERA anti spyware (even buying the pro licence from Avast), and it’s accusing many worms in my PC.
Could you please check my printscreen file to check?
And I think that my Avast is not be able to turn on my firewall, can you please guide me on this situation?
I have no idea if this forum has a support for Brazilian users, somebody speaks portuguese?
Thanks for the attentions, and I’ll be glad with one answer.
Bye bye.
