Installed CIS now no Mafia War on Facebook

I’ve played mafia wars on facebook every since I recovered from my two strokes. I loved Comodo way back then. I’m running Vista 32 with IE8. I’m willing to change anything that will secure my pc and at the same time allow me to be online. I will never be able to work again do to the severe brain injury. So money is a factor. Ane if you give me an answer. Please make it as simple as possible. Because I will proably have to read it at least three times for it to click in. I eventually would like to set this up totally Comodo.
