Just to clarify, the installation path in Program Files (x86) does not define the software's actual architecture or its performance. In Kaspersky, the critical components—specifically the
file system drivers and kernel-mode services—have been native
64-bit for over a decade. In fact, 64-bit Windows (10/11) would not even allow them to load otherwise.
The fact that certain auxiliary modules or the UI reside in the x86 folder is simply a packaging decision common in complex software and
does not affect protection or engine speed. Judging a security suite's capabilities based solely on its installation directory is a technical misconception.
If you have any doubts, you can verify this yourself: open
Task Manager, go to the
Details tab, right-click the headers to 'Select columns,' and check
'Platform.' You will see that Kaspersky’s core processes (like avp.exe) are running natively in 64-bit, regardless of the folder they are stored in.
