Just for your information.
Since I had Windows 8, then 8.1, then Windows 10 Insider Previews, then Windows 10 RTM, I never use a 3rd party AV program.
All I am using is the Windows own Windows Defender as my Real-time Protection, and Malwarebytes free edtion as my On-demand Protection.
I never have security issues. And that's about 3 years now.
Whether you want to employ a 3rd party AV is entirely your choice. I am just telling what I use for reference purpose only.
Would you please tell us whether you use the pay-for Avast edition, or the free edition ?
That's okay. No offense, I just wanted to clarify that I was a she.
I downloaded the drivers today when I downloaded the HP printer software, but I don't know if they are updated. Do I need to first get the printer software installed before installing the drivers? I am not tech savvy at all.
