explorer are not? i just downloaded avast! antivirus software and scanned my whole comp with it. i had one virus so i deleted it. later i try to go on firefox and it pops up and is completely blank and says done on bottom left. i can type in any url and it wont go. if i try to go on internet explorer, it says "internet explorer cannot display the webpage" etc. i have tried uninstalling it and reinstalling it, security settings, and anything else i could think of. safari still works fine but i dont really like it... firefox is my favorite browser and i will be very upset if it wont work anymore. thanks for giving this a look
