Sometimes the cursor changed to strange Sharpes, such as "+", "arrow + a square", "circle with a slash inside."

Then the cursor is NOT easy to control and the computer is slower.

 

Someone hacked me or what?

Cursor is usually changing shape when it hovers some element on the screen e.g. control, border of window etc. After hovering other area (move it), it should return to its normal shape.

Cursor with shape "+" is used by e.g. Paint, and other 2D painting software like Photoshop.

Cursor with shape "circle with a slash inside" means that control that is hovered is currently disabled and cannot be clicked/activated/used.

 

However, in some rare situation, there can be error in application and cursor shape won't return to its normal shape.

 

Also some lame hackers are changing shape of cursor, usually to nothing (hide it), to force user to restart computer.

If you will leave computer with turned on network, they can use startup time to load/update when antivirus was not loaded yet.

From your description, it'll unlikely.

 

ps. Maybe it's result of ClickLock feature? Search Google for "how to enable/disable clicklock feature"..
