|Difficult. I am happy enough with Windows Defender as, I believe, is Johnw. However I know some helpers rate Avast as better then WD and I've no reason to go against that belief - in fact AV ratings seem to often suggest this.|
Sometimes with computers you can get conflicts which possibly come along with the particular hardware and software combination you have on board.
If you want to try something different and Avast has issues with WD being present then I think Bitdefender free is worth looking into. Like WD it is completely unobtrusive, does its thing without hassle and has good ratings too. If you want to try it disable WD real-time option first. It might be best to first use the Avast uninstaller, as already given, to ensure there are no remnants about.
Sorry I have no answer to your particular about substituting WD with Avast. I think it is "just one of those things".
Always pop back and let us know the outcome - thanks
