So if you could only choose between Panda Free or Qihoo 360 Total Security Essential, on a Windows 10 laptop also running Zemana AnitLogger, which AV would you use? I've been good at not changing my AV for several months now, but the itch is back after reading this thread. LOL I've only used Windows Defender and SecureAPlus, until the recent Zemana lifetime offer, and uninstalled it to use Zemana with Windows Defender. But like I said. The itch is back and I like both of those AV's. Avast worries me because of the SFC problem. Thanks.
