I have an Acer, aspire, 5733Z-4851.  It has a 500GB HDD, 4GB of Ram and a P6100 processor.


It has started doing eratic things. When i am typing it will move from the point im typing to another location. Also the mouse is

putting up a strange symbol which looks like a large dot with an arrow pointing away from the dot.??? When i move the mouse 

pointer off the page it goes back to a normal pointer. I dont know if i have picked up some kind of virus or what. I ran AVG, Malwarebytes and superantispyware but still having the problem.

Help Please

Did you disable the touchpad? Sometimes leaving the touchpad on with a mouse can cause the pointer to jump from one place to another while typing.

As for the strange mouse symbol, sometimes pages customize the appearance of your mouse when you visit them.

Check your operating system's mouse pointer settings in Control Panel and try lowering the speed under the Pointer Options tab. When set too fast, the mouse can act quirky and may jump all over the desktop at the slightest touch.

If you have a wireless mouse, low batteries can result in weak, mixed or no signals that can affect its functionality so start by replacing them. If you are using a ball mouse, remove it and clean the rollers as dirt and gunk will cause erratic behavior. If it's an optical or wireless mouse, "jumpiness" and "jerky" movements can result if using it on a glossy surface or reflective mouse pad. In some cases using multiple or uneven mouse pads can produce the same results so as a test, try placing it on a piece of newspaper or rubberized pad to see if that resolves the problem.

If that does not help, confirm that the mouse works on another machine. It is possible the mouse could be defective or has gone bad. Another thing to try is to use a different mouse or a PS2 adapter if its a USB mouse.
If this is an issue on a notebook or laptop, be sure to read Disable Touch Pad of your Laptop; Avoid Erratic Cursor Movement When Typing.

Also be aware that when using a USB wireless peripheral device (i.e mouse, keyboard, headphones) with a computer that also has a USB 3.0 peripheral device plugged in, you may experience erratic behavior caused by interference. This is especially likely when using USB 3.0 remote hard drives or flash drives as described in this article: Wireless product not working properly when also using a USB 3.0 device . In these cases the vendor may have an extension cord which can be used to plug the USB into and move it far enough from the 3.o port to eliminate that interference.
