Right after installing Avast Home Edition I began having a problem keeping voice in Yahoo messenger. I have no problem talking, but lose the ability to hear every 3 to 5 seconds. If I tap the green "talk" button, I can hear again for another 3 to 5 seconds. This happens over & over. As a test, I hooked up my old PC (that has never had Avast on it) and everything works fine. I did NOT have this problem before installing Avast. I have since uninstalled it but the problem remains. Running WinXP Pro, with all Microsoft updates. I feel that a setting still remains, or perhaps an entry in the registry. Any help would be MUCH appreciated.
