Question

hi,this is what happens,i log on to my banks internet website,( co operative) it asks me to put in security information that is obviously some sort of scam,for example it asks me to key in the 4 digits of my security code instead of the normal 2 ,i phoned the bank and they told me to go on a website called pandasecurity and download a virus cleaner which hasnt worked nor has spybot or nod32....please help thank you
