Minecraft Forums

I have deleted my .minecraft folder but still this persists. The world takes a long time to generate but crashes before it can load. This began after I started the download for Windows 10, I do not know if this is related. After installing Windows 10 (Which I am still currently running) this problem still remains. Reasearch I have doe shows that this is a Anti Virus / Firewall problem, which I believe to be a program my parents have installed on my computer (that recently updated) Safe Eyes that is supposed prevent me from going to websites I am not supposed to or whatnot (-.-) and I have no idea what to have my parents do to try and unblock it. Because I have read that it is blocking Java and I have no clue what to have my parents unblock. Here is the crash log:

Thank you for your attention xD

Bump

I also noticed that. Odd. I have never had Windows 8 or 8.1 for that matter, it possibly is because MC does not yet detect Windows 10? I do not know. Honesty I should have waited longer to upgrade to 10 but I could not wait.

Woops meant to reply and I do not see a delete button

what antivirus are you using?

edit, just saw your using safe eyes, this it seems turns out to be a mcafee program (google told me so must be true) the crash you getting is very very common with mcafee, and the only current known fix is to remove mcafee

Yeah Google did not lie to you xD Well unfortunately I can not get rid of it :/ my parents will not let me. The thing is it has not always done this. I have had stupid safe eyes on my computer ever since I built it and I have definitely played MC on it.

Uhmm there are people saying that their error logs say they got 8.1 too even tho they didnt even use windows 8 there possibly is a fix for it but not gonna try and find one now sorry ill private message you when i find something till then just hope someone else finds a fix for it OOPS looks like the mod above posted something at the same time i did xD sorry listen to what he said first LOL

OK thanks!

Many people were using mcafee for a while, but it seems they (mcafee) recently did an update which has made mcafee and minecraft not work together at all

you're epic

Hey I was able to get my parents to turn off safe eyes for a bit, but this problem is still there. Would a full uninstall help? Also, do you think this is a problem that will be fixed by Mcafee?

Quote from webrosc»

removing mcafee is the only fix, not disabling as its still there in the way even when disabled, you would have to contact mcafee about if they plan on a fix or not, but i wouldn't hold my breath there

Ok, thank you sir! Not sure what I am gonna do about this...
