Pop-up virus warning.... advice needed.
I've had one of these months, or years ago but managed to take a screen shot of the problem this time. I have searched for posts similar but I decided I wanted to start my own thread incase it was serious; though I'm not sure it's too bad.
While browsing (sorry, can't remember where; it was general) after clicking on the link I got a pop-up. It has the appearance of a normal Safari pop-up with the compass in the top left corner and the option to 'cancel' or 'ok'. Text was as follows;

Warning!!! Your computer contains various types of adware and viruses.
Your system requires immediate anti virus scan!
Personal Antivirus can perform fast and free virus
and malicious software scan of your computer.
With this pop-up present I could not close the window so I clicked on 'cancel' and then immediately closed the window. I just ran Virus Barrier x5 which I installed as a bit of a novelty last year, and it came back clear.
I had read on some posts that DNS server codes should be added but again I wanted to check this and I also didn't want to use codes posted for someone else. Are they generic?
Also, should I clean out Safaris cache? A little bit of advice on cleaning the cache would be helpful in general actually. When? Why? etc...
Thank you,
