Please read how Symantec describes: Fake App Attack: Fake Scan Website 3
It says in part:
This signature is designed to prevent access to sites that redirect users or perform actions to trick users into installing misleading applications such as fake antivirus software.
The creators of misleading applications often use web pages with fake antivirus scanners in order to convince users to download and run an executable file. They may also use intermediate sites that redirect users from the site they are visiting to another one offering misleading applications for download.
Misleading applications such as fake antivirus scanners (Trojan.FakeAV) or bogus disk defragmenters (UltraDefraggerFraud) are designed to mislead users into thinking that their computer has serious problems that must be fixed by paying for a license of the software. For example, a fake antivirus scanner may perform fake scans of the hard disk and then report multiple non-existent threats....

So why all the alerts? The site is / was probably compromised in some form or another. Here's a perfect example. A Norton user posted at their community forum, asking how to stop the alerts, when visiting the Irish Times website. S/he contacted the site and received (in part) the following response:
"We have successfully traced the fake anti-virus notice to a third party advertisement which was being intermittently delivered to users of The Irish Times web-site in recent days. As of Monday, this advertisement has been blocked from running on our site, and the third party advertisement agency have been alerted to the problem. Despite our team vetting the advertisement before it was launched on July 13th, the advert was subsequently altered by the third party late last week without our knowledge and began to distribute these false messages regarding viruses. "
I would suggest contacting the site owner, if you frequent it often. I would further suggest scanning with the below (FREE) tools to make sure all is "as it should be".
ESET's Online Scanner - Their FAQ and Help sections should answer any questions you might have. (Temporarily disable Norton prior to running the scan)
Best of luck..
I started receiving notices from Norton that they had blocked a Fake App Attack with additional wording, one of which was "Fake Scan Webpage 3". This seemed to be happening about half the time when I went to a particular website (Healthboards.com). I finally went online with a Norton tech who proceeded to completely kill my hard drive. After getting a brand new hard drive and re-installing all my software, including Norton AV, I tried again to go to Healthboards.com and the Norton warning appeared again. The website shuts down after I receive the warning. So what is the deal... is it my computer or the website? I am afraid to use Norton tech support again. Can anybody help?
