Windows 10 comes with antivirus already. Windows Defender. I see computers all the time with antivirus they pay for when Windows Defender comes loaded in the operating system.

Use only one antivirus. Just do a search in the search bar for Windows Defender and you will see it. You will have to remove what other antivirus you have already in order for it to work. It is basic but they really all are.

Why pay for something that you already have for free when using Windows 10.

Use the Firefox browser and there is an add-on built in for adds called uBlock. Firefox is a much safer browser. I only make suggestions because I do this everyday. Take it or leave it
TFC Cleaner from old timer is a cleaner I also use. Googe it, safe web site to download is bleeping computers. It will clean the temp files. I also use ccleaner and have for years but TFC will rid you of things that might be left over after cleaning a computer where ccleaner will not do that. There is a difference in temp files and temporary internet files Cheers.
