Hello,i cannot uninstall the Avira Free Antivirus!

Bad pool error, the program you are trying to install/ uninstall has a conflict with memory access, due to it being reserved by windows 8. it will not allow data to be written to the memory address as windows 8 has sole use to that block of memory/ reserved for the OS.
Dropping into safe mode of windows 8 may allow you to uninstall the program.
