If you mean Windows 8, that is still in beta release, so no surprise you have errors.
Error names and codes?
If you do not know one should never have more than one antivirus program installed on a system, then you should not be running a beta version of Windows 8 (or 9), or anything other than a stock and default operating system.
More than one active and running antivirus will cause system lockups, freezes, blue screens, errors, and will not give you twice the protection, but half of what you have with one antivirus.
Why did you upgrade?
