Any .pdf file that is linked to open in Internet Explorer won't open and will just produce a white background page with a small black rectangle in the top left corner with an X in it. I just ran MBAM and it removed a Trojan (labeled as Trojan.Agent.AMSGen). Could that have something to do with it? I also uninstalled Adobe and reinstalled a new version, but it's still not working. Any help is greatly appreciated!
