Ah that's fair enough, long as it doesn't start nagging for card details or popping up with upgrade messages because you're only on the basic package!
Tbh it sounds like you just want an AV package that does what any decent AV should be doing in that it protects the system without interfering with your use of the computer. For that Windows Defender will do everything you need as it's a full on package.
There's no reason why you can't try a handful out a week at a time and see what you like the best. Windows Defender you never have to open or even look at as it does everything. BitDefender/MWB etc may sometimes fail a definition update and will poll a message in the Windows 10 notification centre with a relevant message of the failure which requires your attention, so you will click on it to see what's up only to see that since that action centre message, the AV has updated but not taken away the previous notification so you've wasted several clicks on nothingI see this every so often on Bitdefender, if an update fails for whatever reason (server error etc) the app will try again until it succeeds, but by nature the Windows action centre message will still be there even after it succeeds. This has been my observation though as I do like to ttry out alternatives from time to time and others experiences may be different.
I use Bitdefender free version and to be honest I never have issues(unless you do a major Windows update to a new version, so best to uninstall and install Bitdefender free version after new Windows 10 version), it's forget and use PC as normal, being cloud based for detection no need to worry on updates as that is taken care of, really nothing for it to do apart from scan for viruses in real time when it needs to.
Great detection and very light on resources with nothing to do really on user end, plus free so no brainer IMHO.
So not bad for essentially 15 months of paid AV for free.
