either you already have a virus on your computer which is downloading malware when you download legitimate programs
if so, what does mcafee detect the trojan as? there should be a name or file/website (don't post the website)
or mcafee is detecting false positive
i think you can rightclick on the icon on the bottom to disable it
or something went wrong in an update and it detects every download as a virus
try reupdating your anti-virus. This happened to avast a few months ago, it made a lot of people freak out :/
if you still have this problem, i recommend switching anti-viruses
avast/avg/microsoft security essentials are good
