I was surfing the web (using Google Chrome), and clicked a link for what appeared to be a scam. When I clicked to close the tab, it wouldn't close (either by me clicking the X, right clicking on it to hit close, or via Task Manager). Something appeared in the icons bar in the lower right, telling me there were viruses/trojans/etc - but it seemed to be trying to get me to buy their product (while acting like a legitimate anti-virus program that was already running). All of my Chrome windows stopped responding, and I restarted my computer - now Chrome is telling me that "This Webpage is not Available" whenever I try to open any website. I can't use the Chrome help function, because that requires the internet... Any help would be appreciated.
