Okay, so I clicked on a normal-looking link to a BlogSpot blog. Instead of taking me to the blog it took me to a website that looks 100% identical to a YouTube page. Where a video would normally start playing it instead said "Video ActiveX Error" and a DMG entitled "1234" that was approximately 750kb automatically downloaded to my computer. I immediately trashed it, but it kind of freaked me out. I know not to click on suspicious links, but this didn't look too out of the ordinary. I guess this goes to show you to be on the look out
