I tried to share a folder on my network and the folder was not visible. I enabled the Windows Sharing rule in the firewall, which did not work. I then disabled the firewall, and that didn't work. I uninstalled Avast and that work. I was able to map the share folder, but I had to use the IP address. Windows did not recognize my computer name. I was able to see the folder on the network and all the files. It behaved as it should. I then reinstalled Avast and now my shared folder is not visible again. What is going on?
