Clicked On Website Link In Yahoo Search / Got Redirected To Blank Page

Yesterday I was browsing the web on Yahoo search like I always do. And I was searching for a well known social web hosting forum.That I was visiting two weeks ago and had no problems getting onto that site then. I will not tell you the link as I do not want anyone else to click on it, as it is not safe.But I clicked on the link from Yahoo search engine but instead of putting me onto the website. I was redirected to a blank page,that said I have got viruses and it needed to scan my computer.And it just closed my web browser,without warning, and started scanning.I tried to stop it but I could not, so I quickly shut down my computer as this brings everything on my computer to a halt. And then I turned my computer back on again everything seemed normal.But I did a scan with Windows Defender and MRT-Malicious Software removal tool,just in case. And it never found any viruses or malware. And using system restore to put my computer back in time to BEFORE the event happened helped,I think.

But when I went round to two of my friends house,the same thing happened to them on their computer.When they tried to go onto that website. And I tried some computers in the Internet cafe. And the same thing happened,so it was not just my computer.But am I right in that the website I visited was trying to install,spyware,a virus or malware on my computer and someone elses computer as well?As I explain the website is a well known and genuine website that I have visited in the past,well two weeks ago in fact. But now it redirects to that page which seems IS trying to install spyware on an unsuspecting persons computer. And it is not just my computer was trying to do it on.So am I right was it spyware or a computer virus,that, that redirect was trying to install on my computer? And if so is there anything we can do about it?As I reported the website link to Google and Yahoo and they have not taken it off of the search engine.
