In installing software, you need to make sure that the software is compatible with the OS you are using. First, what OS version are you currently using? Is it 32-bit or 64-bit? If it’s 32-bit, then the software you install must be 32-bit, not 64-bit. As for the 64-bit OS, you can install 32-bit or 64-bit software. Everything can work well but will be more leverage when using 64-bit.

Well, also make sure the Antivirus program supports the type of Windows you are using, whether Windows 7, Windows 8, or Windows 10. Usually, on the official website, there are terms and conditions for installation. For now, most Antivirus such as Avast, Avira, Kaspersky, and others still support Windows 7. But in the future, it may no longer support it.
