Good security setup.
You can consider to add Sandboxie.
It allows you to "isolate" the operating system and the data stored on the HDD from Internet threats and malware. It is complementary to antivirus and antimalware which must always be present (and regularly updated).
Sandboxie allows you to start any application installed on your PC, limiting the possibilities for action only to a protected area (sandbox).
The operation of Sandboxie is explained on the official website: while, usually, any application (such as the browser or mail client) perform reads and writes directly to disk going eventually to change the configuration of the various areas of Windows, the registry, and so on, Sandboxie provides the ability to launch any program by limiting Its freedom. In particular, the program performed in the sandbox can read the information stored in any area of the system but, instead, write operations are restricted exclusively to the sandbox.
Sandboxie is referred to as freeware because the unregistered version allows you to use almost all the features found in the full version.
