Viruses and Trojans Found!

[Biker1]

I was on my Diamond earlier today surfing.
I entered a topic along the lines of Voltmeters.
I clicked on the site, and alot of Red Text appeared stating that 42 Virus were found along with 30 Trojans. There was a number counter that kept counting upwards really fast.
It was counting the Viruses detected and the Trojans detected.
At the end of the page, there was a prompt asking me if I wanted to initiate an Anti-Virus Progaram to protect my Device from the Attack.
I quickly removed my Battery and all was well.
The above all happened in a matter of seconds.
WTH was that all about?
I thiught it may have been a site that wanted me to click on the Anti-Virus which would have gotten me into alot of trouble. IDK.
