Personally I'm with Drak on this one. I use windows defender and malware bites, plus C cleaner to keep my computer running smoothly.
AVG I'd recommend staying far, far away from. Every version since 2012 has got inaccessibler, to the point that these days even if it does! detect something, you can't even read the warnings or interact with the screen, or heck, even uninstall the damnable thing without sighted assistance. The program really is a menace!
Depending upon your version of windows, you might well have Windows defender preinstalled, it comes with Windows 10 by Default, you can download it for Windows 8 I think but as I've not used windows 8 I'm not sure.
If you have windows defender, you can scan straight from the application menu, or find it in settings.
If you've got something windows defender isn't dealing with, try malware bites:

Most of the miner stuff you run into trackers etc Malware bites will eat quite successfully.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
