When I browsed to http://www.gb64.com/forum I dit get a popup with the following text:
I clicked on the red cross button to close this window. The I was redirected to this site:ATTENTION! If your computer is struck by the spyware, you could suffer data loss, erratic PC behaviour, PC freezes and creahes.

After closing this site, I did get another popup with this test in it:
Clicking the red cross again opens a new windows that tries to download a file named A9installer_77014208.exe, located at scan-my-pc.comHarmful and malicious software detected. These programs may damage your computer and steal your private information. Online Security Scanner requires Antivirus 2009 components to repair your computer. Please click OK to download and install Antivirus 2009 components.
Of course I did not download this file.
I first thought that my PC was infected with some malware, but now I'm absolutely sure that my PC is clean.
Tried to open the site on a PC in a totally different location/network. You guess it, with the same results.
