I'm pretty well computer illiterate, so here goes... I bought a new computer (Dell) and it had Norton Anti-virus on it which was running fine. For some reason it shut off(don't know exactly when it shut off) and I can't get it to run...also, my dad put Mozilla Firefox on and now I can't check my email (hotmail) or get to any of my financial sites (bank, credit card, loan sites) It gives me "The connection was refused when attempting to contact_______". But everything else works fine. I WAS able to get on the sites on Mozilla, but it doesn't work anymore...anyone have these problems??
