Just an hour ago windows vista on my Dell inspiron 1545 popped up saying my laptop is full of viruses and worms. i had a look at the list and it had email worms and viruses and it explained some of the viruses could delete evertyhing on my laptop. I coudn't beleive this as i had brought norton 360 when i brought my laptop and it is installed and up to date. so i did a scan on norton 360 and it showed no signs of any threats. now i don't know which one is telling the truth. SOMEONE PLEASE HELP!!
