misstephgg: you have the basis of a good security setup there (in the past I used to use both AVG free and MBAM free, though these days I've switched from AVG to avast) but you need a few more things. The key things you ought to add are:
Noscript in your browser (makes drive-by attacks almost mpossible), you will have to use firefox browser for this although there might be some similar scriptblockers available for chrome also.
Malwarebytes anti-exploit, there is a free version. This acts as a lyer behind your browser to make drive-bys even more impossible than they would be with noscript alone.
Running an adblocker is alos helpful, although noscript has fairly effective ad blocking as a side-effect of it's script blocking. Adblockplus works well alongside it.
As notes regarding parts of your questions, AVG will scan automatically and provides real-time protection, MBAM free has no real-time components and just acts as an on demand scanner and a cleanup tool if it finds anything. The paid version of MBAM does have real-time features and automated scheduled scanning.
With AVG, mbam free, noscript and MBAE installed then you simply need a few good practices to keep secure. Some of the key ones are to:
Set up windows file explorer so that it will show full file extensions even for known file types, this way you can see if there are any exe files pretending to be other file types.
Never open any file at point of download, instead save it into a folder, then scan it with both MBAM and AVG and then open it if both say it is safe, after checking it isn't an exe or scr file in disguise.
Scan any exe files you deliberately download (this will be when you are downloading programs) with AVG, MBAM free and then with the online scanner virustotal.
Ensure that browsers, plugins, and antivirus are up too date. Alsokeep your operating system up to date with security updates.
Back up your files on external removable devices which are only connected to your computer at th3e times when you are performing a backup, perhaps in non-synced cloud backup services as well.
Back up your system by making a system image, you can recover from this in case of disasters rather than having to do a full reinstall.
Put UAC on it's highest setting, to prompt and ask you on every exe file you try to run.
Make sure the plugins in your browser are either disabled or set to "ask to activate".
