Is it possible/smart to have not one, but TWO anti virus software on your computer?

I have Norton already installed, but I like some features of windows one care. Not only do I have several months remaining on my Norton account, but I'm apprehensive about putting something new on and the possibility that I may not like it after all and would want my Norton back. Therefore, I need to know, if I can keep my Norton installed and proceed to install One care, and in the end have the virus protection of BOTH softwares at the same time. Is it possible? Will they conflict with one another? (Im asking because I know nothing about computers software etc..) Or will they actually work simultaneous, giving me a safer internet experience x 2?

not recommended

cause crashes
Possible YES, Adviseable NO NO NO NO NO NO NO

As said more than 1 will at best cause minor conflicts, false alarms, and at worst could cause significant problems with files being read by 2 apps and could cause system corruption.

Set a recovery point, or ig you have access to a utility like Norton Ghost, image the drive to a backuparea before you uninstall 1 to install the other.
