Hi Norton was scanning like it does every week today and i just happened to walk in while it was going over some files that looked suspicious. There were quite a few of them, including things like Backdoor.Rustock.B. The thing is, Norton didn't detect that as a virus, it just continued and passed over it and many other ones. I also tried a few more scans and they didn't find it either. I was just wondering why this is happening and if it could be a risk. Thanks Edit - This also has not happened on one computer but 2 more in the house, and Norton just passes over them.
