Good alternative to Windows Defender on 8.1

I had to do a format and reinstall on my main rig, and thought I may as well upgrade to 8.1. My only real gripe is my Downloads folder lagging like hell, which I've read is due to Windows Defender. Now I really like MSE/Windows Defender because it's unobtrusive and lets me do what I want to do without pissing me off. Several attempts to try another antivirus program have always resulted in me going back to MSE (either due to viral infection or general annoyance). The lagging, while not an issue per se, is annoying the hell out of me. So I'd like suggestions for a good, free alternative that will be unobtrusive, not try to block everything I want to do (I'm smart enough to know what I'm doing), and not make my PC lag even when running a schedules scan.

Thanks.

 

Windows Defender problem

Hi Ernst,

To troubleshoot this issue, we suggest that you check the Windows Defender service if it's running. If you are using a third party spyware/malware program, it may disable the Windows Defender service. To do this, please follow the steps below:

• Press Windows + R key.
• Type services.msc.
• Right-click Windows Defender service and click
  Start.

Let us know the result.
