I'm infected-I'm not infected what happened?

[newbie111]

Last night I became infected with Vista Antivirus 2011. I'm running Malwarebytes, Avast and AdAware. While surfing the Internet Vista Antivirus 2011 pops up and takes control of my computer. I immediately ran a quick scan of Malwarebytes and it said no threats. Then all my programs closed and I couldn't open up Malwarebytes, IE8 or Mozilla Firefox. I searched the Malwarebytes forum from a different computer and found information on Vista Antivirus 2011. I couldn't figure out how to post a new topic last night so I went to sleep. This morning I wake up and the computer screen now shows no evidence of Vista Antivirus 2011. Task Manager showed Vista Antivirus 2011 isn't running and I'm able to open up Malwarebytes, IE8 and Mozilla Firefox. What happened overnight
