Computer Virus Help Needed

Just for the record, I've had that (and similar) splash/warning page come up a few times.

The first couple times, I simply turned off my computer.

No damage done either time.

Then I started seeing what else I could do...

apparently the program NEEDS you to click on something on that page to execute.

I've even gone so far as to finish what I was doing in other browser windows before restarting my machine.

Hasn't gotten me yet (of course, now that I've said all that.....)

I have seen that myself, and it does seem to stop it sometimes.
Even after scans and everything, nothing.
But I have seen it the other way also, where it comes up and that's it.
Never noticed the clicking something being a requirement though. (I'll have to pay attention to that and see)
Not that anyone ever admits if they did click something. :D
