      I have an old machine running Windows 7 that uses Abelha Digital’s HostsMan (http://www.abelhadigital.com/hostsman/) to block virtually ALL web advertising — the major source of all malware infections, after email attachments.

      I’ve been using it for at least a decade, ever since Fred Langa recommended it in an issue of Windows Secrets, and it’s been just WONDERFUL.

      Meanwhile, I see that this machine is running Windows Defender as a service, and it is constantly using about 48% of the CPU.

      Since Windows Defender for Windows 7 is considered inadequate anyway, I’m inclined to turn it off.  Any comments?

      Thanks to all,

      Windows Defender (the original “anti-malware” version, not the newer “anti-virus” version) had some utility in Vista, where it would alert you if a program was trying to modify the registry. But this feature was removed in Windows 7, and WD became little more than a second-rate scanner. (The program has since been renamed and current versions score highly  in AV detection tests.)

      You can uninstall Windows Defender from your Windows 7 computer with minimal impact on its security. And if it’s sucking up 48% of your CPU cycles, then your PC will actually be better off without WD.
