Something about an invalid signature. I have tried to run as administrator. Still getting the same thing. What can I do? I just want to install my Avast Pro.

Did your new computer come with a preinstalled AV?
Did you remove it according to vendors instructions before installing avast?

It came with McAfee and I already uninstalled it. I've tried turning of Windows Defender to see if that might be causing the issue but it didn't work. I managed to find a link to an offline installer for Avast Pro, downloaded my license file from my account, and now I think it's working fine. Will do a restart and a scan just to be sure.

Did you use the tool from McAfee ?
