From one day to the next, the only program that can access the internet is Internet Explorer. I do not use it otherwise, I only use Firefox. Thunderbird can no longer access the internet, AVG can't, only Internet Explorer. From a command prompt I can ping my router, Google and other internet sites, so my hardware is fine. Any help would be appreciated == This happened == Every time Firefox opened == From one day to the next == == User Agent == Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Win64; x64; Trident/4.0; .NET CLR 2.0.50727; SLCC2; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C)
