Virus help with internet explorer pop up

[j_quigley0]

I opened firefox and got on NijaVideo.net. After I exited out, McAfee told me I had a Trojan, which I removed. Later I had two pop ups from Internet explorer to some software download website asking for my information. Help.

McAfee is constantly telling me about this trojan and this is what it is saying:



McAfee has automatically blocked and quarantined an infected file on your computer. You can restore quarantined files from the Restore pane in SecurityCenter.
