A good antivirus program is a must. Avast is a pretty good one and one of a few quality free ones. It will usually catch anything you click on that is not safe. I am surprised however that it did not block that bitcoin mining.
Great point. I was addressing clicking on a button that the op talked about but I should have thought to mention that good protection is a must these days where a malicious web page or even an ad on a good website page can do bad. I hate that so many of these get through the ad servers.
Thanks for bringing that up.
