Lately when using Safari, I'll click on something on a completely safe website (this one for example), and then as soon as that click event processes, a tab with spam opens up randomly. Do I have some kind of mild virus? I will admit I do go on bad sites like the pirate bay and YIFY for movies, but I'm always very careful when doing so (looking over my digital shoulder, tunneling through a VPN, etc.). Whatever it is, it's rendering Safari near useless because of how slow and erratic this problem is making its behavior. Is it possible to uninstall and reinstall it? Of course that would only help if the problem is buried in my browser; if it's system-deep I've got bigger problems right?
