This is probably a common problem from what I can see but there is no one solution yet.

here is the minecraft launcher log:

Here are all of the solutions I have tried and failed. I already tried reinstalling Java, twice to be exact, I tried logging out of minecraft which only made it so I couldn't log back in (fortunately i had signed in on a different user so I used the launcher profiles txt or whatever to get back on to offline mode)

I tried to unblock minecraft and Javaw.exe from my firewall (AVG) all to no avail. and finally I DO NOT HAVE ANY MCLEAKS!!I

have however researched "SunCertPathBuilderException." apparently its java speak for bad certificates, whatever that means.

I'm sorry if this is a redundant article but if anyone has any solutions I haven't tried please do tell.

You have to turn off AVG LinkScanner

Open the AVG program.
Click the Web Browsing component.
In the LinkScanner Surf-Shield section click the switch to change it to Disabled (red).
In the Online Shield section click the switch to change it to Disabled (red).

No that didn't work, I turned those two things off and nothing, thank you though. even just turning off AVG doesn't do anything. it did occur to me that I have Covenant eyes and that might be blocking something. if that is the case there is nothing I can do about it (I doubt it though because it has reports of what is blocks and I haven't seen anything unusual).

It probably is Covenant Eyes. Their web site isn't very specific about how they work, but the very act of intercepting SSL connections in order to possibly block something will break the SSL security chain and cause this error.
