I upgraded to Go 1.5.1 from 1.4.2 today
0:) Deinstall old version of Go (doc/install)
1:) Download https://storage.googleapis.com/golang/go1.5.1.windows-amd64.msi
2:) Get worried by this message from chrome:
It says that there is something fishy with the download and could be harmful.
3:) Go on and accept it - its from google, so what ...
4:) Go to the download folder and run your virus scanner over the msi:
5:) UhOh - WTF is an Archive Bomb?
6:) Google for Archive Bomb, read Wiki about Zip_bomb
7:) Looks like its detected because of special compression used by bzip2, i feel brave today and go on installing the msi.
8.) Checking again the c:\go folder for viruses - all ok
go version go1.5.1 windows/amd64
Yeah, it works
10:) Recompiling and running some of my most important projects - no problems whatsoever.
