Minecraft crashes when joining or creating a single-player world!

Recently I've had problems with my anti-virus program, Avira. So I uninstalled it and installed Avast. I then update Java to 8.101. This was last night. Minecraft was working fine then and I could play Multiplayer and Singleplayer, with or without mods. Then this morning when I got on, I couldn't do either. My 1.7.10 had mods, and when I removed them, it still didn't work. My 1.10.2 version doesn't have mods. The crash report is the same error.My firewall allows Minecraft and any other launcher for Minecraft that I use.
