When I logged on to my computer this evening, but before I went to the internet, AVAST indicated that a Yahoo file was being moved as a possible infection (I think). When I tried to go to my ATT Yahoo homepage, a message comes up that the internet connection has stopped working - the problem may be in the Internet Explorer program as it is the program which takes me to the ATT Yahoo home page. I was able to connect this morning. I suspect that the AVAST program deleted the file that provides the ATT Yahoo connection. Is there a place from which that file can be retrieved? I am able to connect to the internet through Google Chrome. Thanks
