I am running Windows 10, Pro apparently. AMD A6-3620 APU with Radeon HD Graphics 2.2 GHz, 6.00 GB (5.49 GB usable), 64 bit OS, x64 based processor, Touch support with 2 touch points. Windows 10 has a somewhat irritating habit of updating itself without asking if I want it to, so I am not exactly sure when this happened, but probably within about the last month. I recently noticed that my start button had stopped working (most apps I use regularly I have on the task bar so I seldom use the start button to access them), and I managed to fix that, but I have not been able to find anything on this issue. I believe they started around the same time, although the closures may have started earlier. I can't be sure on that, only that I noticed them earlier. What is happening is that my cursor will flick up to the top right and close a program even if I'm working on it. I do not touch or bump the mouse. There does not seem to be any rhyme or reason to when it happens. My current workaround is to make the active windows of any programs I am running smaller than full-screen so that when the cursor flicks up there, it can't close anything because the top right of my window is to the left of the target point. The cursor also sometimes randomly jumps to another area of the screen. I am thinking I must have a virus of some kind, but searches have not revealed anything, and so I am a bit stumped. I am running AVG free, and it is up to date and runs automatically. I have looked at some of the logs and things for other similar reports, but they are on older OS and the issues did not seem to be close enough to my experience to be worth trying to replicate the reports requested (I have an assignment due, had forgotten to make Word smaller than full screen - thank goodness it asks if I want to save before closing!) without more clarification of what you might actually need. If anyone is able to assist, I would appreciate it greatly. I can check in again after my assignment has been turned in tonight. While I have some basic skills, I also have some glaring knowledge gaps, so I may need to come back with more questions to instructions. I don't know if it is relevant, but I have a wireless mouse, it's a microsoft one. I appreciate your help.
