Do antiviruses slow you down? Well, depends on whether you choose a well-optimized antivirus or not. I've tested a lot of the best antivirus 2025 contenders to see which providers impact my system the least while still offering solid protection, and I'm here to share my results…

--------------------------------
Norton Antivirus

Norton antivirus is probably not the first thing that comes to mind when hearing the word "lightweight", but even with all those features, it manages to show some impressive performance. In the latest AV-Test report, Norton showed great results. Jumping to my testing results, just like TotalAV, Norton caught all 10 malware files.

--------------------------------
Bitdefender

Alright, my last recommended antivirus for Windows 10 is none other than your beloved Bitdefender. This sleek and lightweight antivirus can be perfect for older Windows devices. But how does Bitdefender fare on my test? Great!— it managed to catch all 10 malware files.

--------------------------------

TotalAV

It has great protection and comes with a nice selection of useful system optimization tools. So, first, let's check out independent testing results: once the files are nice and cozy getting ready to do some damage to my PC, I can start the full scan. The first good news is that the scan took less than 10 minutes to finish and TotalAV antivirus performance was at most about 60% of my CPU, but it caught all 10 malicious files!

Honorable mentions - NordVPN + Surfshark

I want to complete this best antivirus for Windows 10 list with 2 honorable mentions - Surfshark Antivirus and NordVPN Threat Protection. These are a combo of lightweight Windows antivirus and top-of-the-class VPN solutions. Although they still have a lot to grow in device protection and Windows optimization spheres, I consider them valuable options for older or weaker devices.
