Will this fix work for Windows 8.1 x64 with media center? For the past month or so every time a scan runs my computer just completely locks up. I've have reinstalled windows I have reinstalled McAfee, I have run sfc and chkdsk numerous times which seems there are no corrupt files anywhere. I'm more than a tad bit frustrated; I mean considering every time this scan runs my computer just locks up for hours until I have to force my pc to shutdown... I'd love to be able to run a full scan and be able to rest assured that I have no viruses (which I doubt that I do have, since I rarely download anything and try to avoid unsafe sites), but how can I rest assured when my McAfee All Access can not run a full scan?
