First SFC does not correct registry errors. Also out of the hundreds (could be thousands) of Windows PCs I've worked on in the past decade I've yet to find a registry error. That is something that FIX IT PC APPS use to sell their awful apps to the unknowing.
Second, if Avira is removing a bug, we want to know how this got on your system. We need to cut off all the heads of the Hydra. Plus removal does not undo damage.
Finally I've seen this with failing HDDs. Let's check up on that. Supply your Web Speccy link if you don't know how to read the HDD SMART VALUES in a Speccy report in a reply to the forum.

As to resets there are factory resets and a lighter weight reset where you reset W10 and save your files. It's under "Keep my files" as you expand the section "Reset your PC" at
So my issues are twofold but both symptoms started at the same time. I am using Windows 10.
1. The mouse pointer keeps flashing the blue circle every other second. Unfortunately this is impeding my ability to run media. Youtube videos and games would stutter according to when the blue circle flashes. Other programs are being stunted as well.
2. Taskbar freezes/unresponsive after a certain period of usage. When this happens, the action bar, start menu button, and search bar on the bottom are non responsive. Sometimes I can't even right click icons on the task bar.
I use Avira for my antivirus. I remember the previous night I had shut down my computer while avira was in the process of getting rid of a bug. I did an SFC check to look for registry errors but that did not solve the problem.
I'm considering resetting my computer but I hope it doesn't come do this.
