Confirmed bug? Maybe they need to tell their 24x7 support. I called in last night and the guy told me that it was a problem with the program I was using, not Avast. I was using Windows Explorer to share files! The guy kept referring to my LAN as the Internet! Dude, big difference between my LAN and the Internet.
I had been using the free Avast AV, but decided I needed a little more protection. I guess Avast decided I needed a lot more protection by keeping me from sharing files, and printers. I hope this gets fixed soon. I'm going to try the troubleshooting tip mentioned above. If that doesn't work, I might revert back to the free AV until they get this fixed.
