Hi, so I tried your product, hoping it would give me a little extra "push" for my system. It appears, though, that something went wrong. My action center notification on my task bar continuously pops in and out. This is distracting and annoying as I auto-hide my taskbar, and it drags the bar back down, then up again. Repeat, ad-nauseam. Not only that, but it is telling me that my anti-virus (both Avast! and Windows Defender) is turned off. WD is turned off, but Avast! is not. I'm assuming this is causing the pop up message, but I can't tell as it too quick to read. I've tried using system restore, and NONE of my restore points work any longer. Unfortunately I did not back up my registry. I am running Windows 8.1. Asus K55A (laptop). If you need any more info, I'd be more than happy to provide it, but would be much more happy if I could get this resolved. Thanks for the freeware, and your time. Hope to hear from you soon.
