There is never one weird trick discovered by a housewife in your area. There are never three tricks that will make you harder, better, faster, or stronger. As for the ad, you just got taken to an ad bomb site. They make money on people clicking through and then they display a ton of banner ads.
As for giving you malware, it certainly is the type of site that would give you something. You can bet it was looking at your browser and OS trying to see if you were using one with some particular weakness.
I was using Mac OSX 10.6 when I encountered this back in 2011. Browser? I might have been using Firefox or Chrome at the time. No problems since but I've scanned using ClamXav just now to check to see if I got anything malicious installed. No threats found.
Odds are, virus or just weird troll. Get rich ads are usually spam/viruses. Get rich ads with downloads are more likely to be viruses. Get rich ads that say they have a download but actually don't is just very poor design/slightly better made virus/troll. Assume it's a slightly better made virus until you get rid of it if it is there.
I encountered this back in 2011. No issues since after leaving that site but I gotta make sure my computer is clean and make sure no one clicks that ad for the website I'm running if it does try to be part of my site. At the time I was using Mac OSX 10.6 (Apple sucks I know but my next computer won't be an Apple computer) but I don't wanna get cocky. There's malicious software developed for Mac OS too.
