Not trying to be rude, but really what it says, IMHO, Norton didn't catch it, or it would have told you the virus was there and was stopped. Check Norton's logs if it detected the virus it will report detected and action taken. OR, AVAST had a false positive, which happens too.
The site link http://pmaconcessions.com/index.html is not the culprit, apparently an ad or a piece of content that is used in a Iframe is the one with the trojan.
If you think this is harmless, think again, your browser could be hijacked for a long period of time, by taking you to sites that you were not even clicking on. Who knows how harmless or how devious this particular trojan is. For 6 months I had to endure a Trojan that was hijacking my browser, using google searches. Every other time I entered a search and clicked on a link I would be taken to a totally different site. Avast couldn't detect it, nor could Superantispyware, or several online virus/trojan detectors. I subscribe to Superantispyware, human anaylsis and they couldn't figure it out either. Finally both Avast and Superantispyware caught it and now I have no problem.
Here is a Recent comparative Rating of most popular AV software
I came across this when reading a user comments on different AV software, there are dozens of sites rating AV software and whoever paid them the most money will be ranked first. IMHO McAfee and Norton are big resource hogs and do only a fair job compared to several other AV Free software programs available. Norton and McAfee do a good job on an enterprise level where they get the big bucks, but personal level protection for home PCs they both have been ranked fairly low in a lot of independant studies over the years. What you really want is Real Time protection, you don't want to turn your PC off and then when rebooting you are warned, it could be too late then.
Again the purpose of even mentioning all this, is to help anyone struggling with Virus/trojan issues. If your happy with the security software you are using then ignore the above.
