poisonous spider on my porch

I went out to get the newspaper and I see this huge spider one of my moms friends thought it was a banana so my mom search the web and found some pics of banana spiders and also found a wiki answer to this question: are banana spiders poisonous?

here's what some people said:
The Banana Spider is known to hide among bananas shipped to the US and is really called the Brazilian Wandering Spider. These spiders are aggressive and very venomous and not intimidated by size (can attack people when threatened).
The odd part about the Banana Spider is that studies indicate only 33% of the spider bites actually contain any significant amount of venom, but those that are injected with venom could be in serious danger!!!!!!
If you are bitten by a Brazilian Wandering spider (Phoneutria spp.), you should seek immediate emergency treatment as the venom could possibly be life threatening. The Phoneutria not only has a potent neurotoxin, but is said to have one of the most excruciatingly painful spider bites of all spiders due to its high concentration of serotonin.
Despite the Banana Spider's reputation as the world's deadliest spider, there are multiple studies that dispute the ability for the spider to actually kill a human and one study suggested that a little over 2% of these spider bites (mostly in children) were serious enough to require antivenom.
On the other hand, there are other studies suggesting that the Banana Spider is indeed the most toxic spider in the world based upon toxicology studies. One of the most notable and thorough studies is presented in the book "Venomous Animals and their Venoms Vol. III" by Wolfgang Bucheral and Eleanor Buckley. This study has some shocking findings that clearly demonstrate how lethal the Brazilian Wandering spider can actually be.
There is an antidote for the bite of a Banana Spider and was discovered by Carlos Chagas from Brazil.
If you see a spider hiding in a cluster of Bananas, you should move right along and possibly inform the store manager that it may be a Banana Spider!

Answer 2: 
First: All spiders are poisonous, as it is part of their eating mechanism / biology.

Second: There are two types of spiders called "Banana Spiders":
