Hello,
If you want to use paid product, my choice is Emsisoft.
If you want free antivirus (In my opinion free softwares more than enough) I can suggest you
Avira Free &
Avast Free.
Use offline installers and watch out their software offers!
I love the config that you have, it is basic and it can be good.
I just want to strenghten your browser, because all malwares come via this channel.. add these extensions
-
HTTPS Everywhere
-
WOT
- use
uBlock instead of current adblockers you have. (uBlock is amazing blocking extension)
and
CCleaner for tweaking and cleaning your PC regularly (daily clean my favaorite) Watch out the installer it offers other programs while installing, but CCleaner is very good product
