We have recently gotten infected by avatin.com fake antispyware. I've been searching the www and cannot find an open source to get rid of it. How do I get rid of this? The porno.com and viagra.com website popups are getting rather annoying.1 person needs an answerI do too

I suggest to go to:http://onecare.live.com/site/en-us/default.htmAnd run full system scan.If it fail and you cannot remove it then contact Microsoft Safety Support:https://consumersecuritysupport.microsoft.com/default.aspx?productkey=pcsafetymalware&faq=1&task=diagnostics&st=1&wfxredirect=1
