I would consider making the move to Windows 10 before the free upgrade ends.Although I believe Ahnlab is not Windows 10 compatible.
Ahnlab has not done very well in AV tests and its scan could be much more thorough(very low numbers of scanned files)
It is probably better than nothing at all but there are many better options for the same price or less.
There are also better free AV options when combined with some other programs and Windows Firewall that would probably serve you better.
Most have free trials and it is always worth giving something else a try.
I would consider CCleaner as that is usually more than enough for privacy & optimization.
Thanks for sharing your config
