Let me tell you the truth, actually there’s no need to have an ‘external’ antivirus these days IMHO:
Android has inline Play! Protect protection.
Windows has inline Defender protection.
There’s a lot of advantage of what inline protection has:
- fresh updates
- accurate updates
- full range of updates
And all of these are in the background…
But there’s some disadvantages of the default protection:
- VPN not included
Unfortunately no fresh protection without updated definition files, so updating proper protection is pretty important though.
