I use Firefox 42. I was visiting the Daily Mail news website. I was using a new laptop and I'm not used to the touch pad on this one. I accidentally clicked on an ad. It pulled up a site. It said that the site was suspected of having malware or something. I don't know if this was an attempt at social engineering or actual Firefox security measures. It said that it was analyzing the site. A loading bar went across the screen and said it found vulnerability's and the download box pop up appeared. I closed that tab and the download book was still there. I took a look to see if it was the real box that Firefox has and closed it. After a few minutes and then closing out Firefox my laptop says that there are no Wi-Fi networks available. I know that is not true because all my other devices detect many. A couple of odd things to add. First that dangerous website is not in the Firefox history log. Second, I was downloading a patch for Star wars the old republic. It continued downloading after my computer said that it couldn't find a connection. That was the only thing that was able to connect to the internet. However after closing it, it is unable to connect just like everything else. I ran a full system scan with McAfee and it didn't find anything. I will restart my computer and hope for the best. update The McAfee tool getsup found three suspicious items. The tool sent samples to McAfee lab for examination. It ran an automated examination and could not find any matches. The samples are going to be examined by McAfee security researchers. I will be contacted via email when they are done. I will then provide an update here.
