A double-wammy fake PornTube site
Landing on the following site not only prompts you with a fake "video decoder" ... look at the fake Antivirus scanner that tries to trick the visitor into thinking they are infected ... well you will be if you click either of these ...

As usual this download is not very well detected ... VirusTotal results here ... ThreatExpert has a detailed report of what happens to your machine should you become infected ... this one is very nasty!
"vidsxxxtube. com" redirects the download (3913181.exe) to a IP address - detected as "Win32/Adware.IeDefender.NIC"

Although the Registrars and Hosting services shutdown hundreds of these type sites each week ... it seems that even more pop-up to take their place. As usual it's all about the almighty $$$ ... these Registrars charge these culprits for registering, then shut them down several weeks later ... only to claim that they are doing their part to combat the spread of malicious sites ... yeah right! ... then why do they continue to do business with the same culprits over and over? = $$$
