All the crashes are the same, so the problem is either wininit.exe or your AV program. Do a search on your system for wininit.exe to see how many instances of it you have. If you only have one, in C:\Windows\system32, then uninstall Avira AV and see if the crashes stop. You can also try uninstalling and then reinstalling Avira.
