Hi Marcoaurelio,

I'm afraid this is an English-only speaking forum. Would you mind posting your question in English maybe we would be able to help you?

Hi, hi , hi, Madasan!!, Sorry, I thought that could use the Portuguese language. But, the question is: The site-http :/ / radardedescontos.com.br / discounts-para-sao-jose-dos-campos.html - opens my Firefox, regardless of my will and displays advertisements that do not interest me in nothing.If the browser is closed the damned intruder opens it at any time to show things that do not interest me.I've tried contacting the owner bloodthirsty, but was in vain,useless.They have no ethics.Help.Please help me.And thank's a lot for your good will.

Do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.
