Be aware though. About a year ago my laptop began to slow up drastically. I began the usual search for the trouble, even contacted a Microsoft company geek, who took over my pc to search for the trouble. Thats really weird watch you pointer going through all your files. When he'd finished he said '' Shucks, Oh my Gud I can't find anything wrong, I suggest buying and installing a new W10. Oh My Gud, I thought. by now my PC had almost died. I went through all my files and then one by one uninstalling likely programs that might have caused it. When I uninstalled Malwarebites, bing!!! all came alive again. This performance took me two days to do cos the laptop was almost dead. Oh my Gud was I pleased and that I'd beaten a Microsoft exspurt at it. Malwarebites was obviouslly interfering with W Defender and it didn't like it. I still have Malwarebytes on my old W7 pc though because it is very good.
