Since Microsoft is dropping updates/support for MS Sec Essentials on Win7 platform... I have a PC (Win7-64) used exclusively for home music studio work, which requires a low overhead and minimal operating system "interruptions" which could impact music production. The PC is offline for music work, however, I do connect to the web temporarily for downloading updates, new product trials, etc. PC is connected via WiFi external adapter. I have been using Security Essentials for last couple years, and it seems to not require resources that interrupt music production. Several software products that I use will not run on Win10. As support is now ended for both Win7 and MS SecEss, I'm asking for guidance on a basic AV product that provides protection but minimizes operating system overhead, if such is possible. Willing to test-try a couple products to confirm no interruptions. I do weekly backups of the PC using Macrium Reflect. Also, I prefer paying for a product that provides better vendor and forum support. PS: On my Win10 desktop I use both Comodo and WinDefender (not sure if I need to use Defender).
