I haven't played since 1.7.5 and my 1.7.5 world loads perfectly, but I updated the game to 1.8.3 (latest) and the game crashes when I load the world. I tried a new world and get the same result. I reinstalled java 8, downgraded to java 7 and reinstalled MC (deleted .minecraft folder) aaaaand it still crashes when trying to load a world...
Here's the crashes report:

According to this bug report it is caused by your antivirus/firewall blocking the game from accessing the network; you'll have to tell whatever you are using to let Minecraft (or Java) to access it.
Unfortunately, they aren't that helpful in providing a solution; "Please visit the #minecrafthelp channel for further support.", which just brings me to a login screen. However, one user said they had Avast and if that is the case for you may try making an exclusion, for javaw.exe (click on edit profile in the launcher and in the advanced Java settings section at the bottom you should see a path to the Java executable; check the box if necessary so you can copy the contents); note that Minecraft.exe is just the launcher.
If you have a different AV you should be able to find out how to add an exception for a program; they all have similar methods.
Note that excluding Java from real-time protection may not be the best idea but if you are using the latest launcher it should be using its own internal version of Java, which should be safer than the "regular" version.

Thank you for the detailed response.
I have gone into AVG antivirus, microsoft security essentials and windows firewall to add an exception for javaw.exe, found using the path on the minecraft launcher as you mentioned. Yet I'm still crashing on world load. I went back into windows firewall and found there are now 2 javaw.exe listed, one with home/work ticked and one with public ticked. I unticked public on one of them and ticked home/work, so now both are home/work. Relaunched minecraft and same crash. Now there are 3 javaw.exe listed, 2 i previously ticked home/work and now a third with only public ticked. I clicked details and all 3 lead to the same path, same as the one found on the minecraft launcher.
Here's the crashes report:

Please send help!
Yes I tried to make a new world in 1.8.3 and got the same results -> crash :/
How come?
Umm... it's kind of why I'm here. Hoping someone can help me out

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
Thank you for the detailed response.
I have gone into AVG antivirus, microsoft security essentials and windows firewall to add an exception for javaw.exe, found using the path on the minecraft launcher as you mentioned. Yet I'm still crashing on world load. I went back into windows firewall and found there are now 2 javaw.exe listed, one with home/work ticked and one with public ticked. I unticked public on one of them and ticked home/work, so now both are home/work. Relaunched minecraft and same crash. Now there are 3 javaw.exe listed, 2 i previously ticked home/work and now a third with only public ticked. I clicked details and all 3 lead to the same path, same as the one found on the minecraft launcher.
Is there anything I missed or could attempt?
thx man
I have encountered the same crash report when trying to run Version 1.8.7. Does the solution posted by test47111 work? It seems it is java problem?
Thank you.
