Hi, I'm new and I have basic knowledge about computer security, please if you can be patient with me . I wanted to present this situation, since yesterday I can not navigates websites .org. Two days ago, a friend used a pendrive which contained trojans and other viruses, but Avira detected it. And then this happend, I do not know what to do, just in case I installed Avast but the pc got slow (obviously, with two antivirus) and uninstalled it in case it was the problem but still the same.

Every time i want to connect a site like .org, this came: Google Chrome could not find the page ...

It's the same for Firefox and Internet explorer. I have asked other people to connect to those pages from other computers, and the websites work perfectly.So, is my pc.

I never had this kind of problem to connect to any site.
I have no ADSL modem but a cell phone modem, and I installed the extensions sriptsafe and Ghostery in Chrome ,if it's worth the mention, like two months ago. And there was nothing wrong with sites .org either, until yesterday.



Thank you very much.
