About a week ago, out of nowhere, there were some programs on my computer that won't connect to the internet. Some of these programs are Google Chrome, Internet Explorer, Windows Media Player, and iTunes. I thought it could possibly a virus/malware (which it still could be) so I downloaded and installed AVG and Adaware. Both of these programs picked up nothing. I also tried installing Avast and Spybot, but when I'm installing, the installer ALSO can't connect to the internet. This has just been getting on my nerves. I'm pretty sure its not my firewall. Its turned off. If anybody could help that would be awesome.
