The question would seem to be kind of academic, since you don't need to pay
for a very good - possibly the best - AV (antivirus) software, given that there's a perfectly good free one that comes bundled with Windows 10 in Windows Defender.
Windows Defender includes a Firewall and
an AV (which was previously named MSE - Microsoft Security Essentials). All you need to do is enable
that AV in the OS, and away you go. However some OEM installations actually disable the MSE component, and nag you to pay for a pre-installed AV package (Norton/Symantec seem to be notorious for doing that). Maybe that is happening in your case.
If it is
what is happening in your case, then you will probably first have to remove all traces of Norton/Symantec or whatever you have, before the MSE AV can be enabled. That was what happened with one of my laptops, at any rate. I used RevoUninstaller
($FREE version) to uninstall any proggies related to "Norton" " or "Symantec", then I used Everything
to search up all left-over files/folders related to "Norton" " or "Symantec" (including in the Windows Store cache) and deleted them, then ran CCleaner
($FREE version) to remove any left-over Registry hooks. Those AVs were almost as bad as a virus/malware.

What antivirus I can for my windows 10 Privacy and protection?Just stick with Windows Defender for AV - possibly supplementing with MalwareBytes AntiMalware - but read this.
As for "privacy", you might want to read this. O&O Shutup10 doesn't seem too bad, though.
- where your question was:
What antivirus I can for my windows 10 Privacy and protection?@f0dder's
advice is very good in that it seems to be consistent with the discovery/experience of many Windows PC users in this forum (i.e., it is not just an unfounded opinion). If you search the discussions in the forum, you will find various useful threads on MSE
(Microsoft Security Essentials) and MalwareBytes
Of course, if you want to, or prefer to pay
for an AV proggy such as Avira, then go ahead - knock yourself out - but then, why worry about the value of a discount coupon for an Avira subscription?
