Microsoft word,sign ins & Adblock Plus?

I just did a system restore to my pc cuz I had some spyweres and stuff but now I deleted them.

1: and I have some probs like when entering something like yahoo answers I just sign in once for 2weeks and other games and all I just sign in once and I do the rember me button and I don鈥檛 need to sign in again but why each time I need to do it now?

2: and usually when I spell check in my Microsoft it tells me how much words,phrases,letters, ect I had now it just tells me that small icon...spell check and grammar complete how can I make it back how it was before?

3: And I had this add-on in my firefox addblock plus I donnu its not blocking adds automatically but I need to do them manually can anyone tell me y?

Thanks in advance
