F-Secure scans on write. Not sure if it scans on access too. The Avira engine is very light it seems and F-Secure probably has further optimized it to make it even lighter.You can test that by downloading malware (even eicar will do). If it deletes it immediately, it scans on write as well. If it deletes it after you right-click the file, it scans on-access. If it deletes it after you open it, it’s only on-execution.
You might need to turn web-blocking off for this test.
