It seems that on the previous weeks, when someone was visiting any of my pages, was asked to install an unknown software in their computer. Sorry to all the visitors: I was not aware of that, and I am not directly responsible of it. Seems that any of the 3rd party services I use in my web page, was redirecting to this application to install.
I hope nobody has installed the application. If somebody has installed it, I believe SpyBot could help him to tidy up his system, and to remove this and other undesired applications.
