Hello,I really really need help right
now. My pc has been unprotected for
days. Mcafee is expired. I'm having
issues installing avast premier which i
sent onto a flash drive from a friend's
computer and its doesn't move
beyond the part where the windows
prompt come up whenever i try to
install it. So im basically down to
windows defender, and it
automatically is off and won't come
on. Its saying the app has been turned
off and isn't monitoring my computer.
I need help installing the avast
premier and turning windows
defender back on for good. Thanks.

With Windows 8.1 Windows Defender will disable itself when another antivirus is installed.

 

Did you use the McAfee Uninstall Tool to uninstall it?

 

Have you tried downloading Avast to this computer?


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

The correct way to remove McAfee is through its program folder via Start > All Programs or by Programs and Features (Add/Remove Programs) in Control Panel, reboot when done, and then run the McAfee Consumer Products Removal tool (MCPR).Note: Sometimes the uninstall works more effectively if you first stop and disable the program's service (and associated processes in Task Manager) or perform the removal in safe mode so there are less processes which can interfere with the uninstallation.

Once McAfee is completely removed, you should be able to install avast!.

I would just ignore any messages/alerts from Defender and just disable it since you are going to install avast.
