I have tried uninstalling Avast using Revo Uninstaller but still keep getting error messages.

Hi there i am new to this and not very savvy so please bear with me when i try to install Free Avg Antivirus it asks me to uninstall online armor before installing i am reluctant to do this as oa is my security is there a free antivirus out there that i can install without uninstalling OA or maybe someone can walk me thru if not. I have Avast but it is not working and i can,t uninstall it or remove it.
