I was on bulbapedia main page and it said I needed to download an ocx file from Microsoft to view any more pages, so I clicked ok when the message appeared and my McAfee said I had a trojan and got rid of it. I did not think it was the ocx add on that was needed, so I tried again and got the trojan again. Think the page is ok I am using Internet Explorer 7. Crashed once when I did not click ok to the ocx file. Usually ok, just wondered why that happened?
