Computer related problem

I was browsing today on a common gaming site I visit that utilizes the website invisionfree as the base for the forums. They have a chatbox on the top, but today, not like other days, it did not work. Instead (because I have a firefox) I received a pop up prompting me to download the application/ octet-stream from: http://www4.cbox.ws

Obviously without it, the chatbox doesn't work. But I don't know how to run it, as the browser asks you which program to use (I don't know why it suddenly did this), and I have no idea what to tell it to use. I was previously using AdBlock Plus to block some annoying music if that helps.

appication/octet-stream is a generic header for any file type I believe. It's basically just a force you to download thing. I didn't bother visiting the site. All I can say is good luck with trying to figure out the problem.

I figured it out. It was basically that my Java had not been updated on Firefox, so it was impeding the chatbox to show up.

I was more focused today though on a fraud antivirus on the internet that told me I had like 300 trojans and 200 some worms. I did a spyware scan and figured out it was just some malware in the guise of an antivirus (I think it's called Antivirus 360), yet I had stupidly downloaded it, and it would give me a message every 10 seconds telling me I had to purchase the antivirus premium so I could save my computer from crashing. I got rid of the program on my desktop, but the malware doesn't appear as a program in the uninstall list (my other hint), so I'm going to probably have to use a program deleter as the spyware scanner I have cannot delete the "program" for some reason.
